This example uses D3 v4 to create a chained text animation where each word or letter is drawn with particle effects. Text is displayed as styled headers, and SVG paths are generated for each line of text. A canvas-based particle system then traces these paths over time, spawning thousands of glowing stars that follow the path geometry. The animation chains through each header sequentially, using SVG paths to guide the particles and CSS filters (blur and contrast) plus a lighter blend mode to create glowing, overlapping star trails. Once the primary text is drawn, the animation resets and repeats with a different star texture, giving the effect of a continuous, generative starfield writing out phrases. The visualization runs as a full-screen background, with large typographic elements acting as both text and canvas for the particle motion.# Stars ## Description "Stars" is a captivating data-art visualization that transforms text into a spectacular particle explosion rendered as a constellation of stars. The visualization presents a sequence of words and phrases, each materializing through a chained particle animation that draws the text along SVG paths. ## Visual Design The visualization uses a dark (#111111) background with a starfield of glowing particles rendered on a canvas layer. Text is displayed in a handwritten-style font, with the final word of the sequence shown in a rainbow of colors, where each letter cycles through five hues. The particle system uses a "lighter" blend mode with blur and contrast filters to create glowing, ethereal effects. ## Animation Technique The core experience is a chained transition: each phrase is drawn as particles traveling along a hidden SVG path, creating the illusion of text being sketched by stardust. The code uses D3's transition system with `attrTween` to move particles along paths while simultaneously spawning new particles from an emitter positioned at the stroke's leading edge. As the path transitions complete sequentially, particles continue to be emitted, eventually transitioning to a final image texture. Key implementation details: - **Particle system**: up to 2,000 particles rendered on canvas with `lighter` blend mode, blur and contrast filters - **Text rendering**: HTML headings overlaid on canvas, with letters wrapped in spans for individual styling - **Chained transitions**: D3 transitions orchestrated to animate text into paths, then particles follow the paths - **Dual particle systems**: The second particle system switches textures mid-animation (white stars to colored stars), creating a visual reveal Notably, the original code contains an incomplete loop in transitionLast, where the for loop stops after the first iteration and the animation does not complete. This suggests the code is a work in progress, with the final stage designed to spawn particles along the last text element's path. data: none The author's explanation, if any, has not been provided.

Text is displayed in a sequence, with each header drawn along a hidden SVG path by a swarm of star-shaped particles using canvas. A custom particle system uses a star texture, additive blending, and blur/contrast filters to create glowing trails. D3 v4 orchestrates chained transitions, moving particles along each path to spell out words, then triggering the next header. The animation concludes with a final burst of particles from the last string, using a different texture to complete the effect. The result is a fluid, text-reveal animation where type is drawn as if by stardust.

Text Transition II

A randomly generated integer fades in and out inside a large headline, replacing itself with a new value on each cycle. The example demonstrates a text transition technique that uses `d3.select` and `d3.transition` to create a repeating animation. On each start event, `d3.active` removes the old heading while a new `h1` element is appended, initially transparent, and its opacity is tweened from 0 to 1 using the `style` method. The process repeats indefinitely with a 1.5-second delay, showcasing D3’s ability to manage enter, update, and exit sequences for text elements.

This example animates a starfield particle system along the path of text elements, creating the effect of text being drawn by moving particles. Three phrases in the Indie Flower font are displayed as `<h1>` elements, each with an invisible SVG path overlay that guides the particle animation. Stars are emitted along each path in sequence, leaving a trail of glowing particles that gradually traces each line of text. The animation then transitions to a second star texture, and the text is fully revealed. The visualization combines HTML, SVG, and canvas, with the canvas rendering the star particles while SVG paths control the animation trajectories. The text is styled with a color gradient, and the animation loops through all text elements, creating an engaging, dynamic intro effect. The code relies on D3 v5 for transitions and path manipulation, with the particle system implemented using the HTML5 canvas API. The example is available under an MIT license. Generated with assistance from ChatGPT.# Stars This visualization creates an animated intro sequence where star particles trace and reveal text. Using `<h1>` elements for text and `<canvas>` for particle rendering, each line of text is revealed by a cascade of glowing star particles that flow along invisible paths, with a smooth color gradient applied to the typography. The animation begins by loading the Google Font "Indie Flower", then displays the text and generates hidden SVG paths for each line. Stars are spawned along these paths using the HTML5 canvas API, creating the effect of text being drawn by sparkling particles. The animation progresses through the text lines sequentially, and after all lines are traced, a second particle system triggers an explosion effect. The visualization combines SVG for text paths, canvas for the star field, and D3 transitions for animation. The star texture switches to a different sprite for the final explosion, and the blend modes and filters create a glowing, dreamlike visual effect against a dark background. The text is positioned absolutely in a container div, with the paths overlaid on top. This creates a layered effect where the text appears to be formed by the animated particles.# Stars This visualization creates an animated text intro where particle systems trace out text along SVG paths. Each line of text ("The font-family of this text", "is", "Indie Flower") is revealed sequentially as a cascade of star particles that stream along horizontal paths, creating a glowing, handwritten effect. ## Key Implementation Details **Text Rendering:** Uses `<h1>` elements overlaid with SVG `<path>` elements that define the trajectory for particle animation. The paths are hidden but guide particle movement. **Particle System:** A custom `App` class spawns star-shaped particles (up to 2000) from a canvas texture, using blur and contrast filters with a `lighter` blend mode for a glowing effect. **Animation:** D3 transitions move particles along each text line's path (from left to right) with `attrTween`, using path `.getPointAtLength()` to trace positions. Headers fade in sequentially as their corresponding particle paths activate. After the first pass, the star texture switches color and the particles "explode" from the text. **Text Rendering:** The "Indie Flower" Google font is loaded via WebFont before the text and paths are created. **Key Implementation Details:** - Paths are computed from the `<h1>` bounding boxes to determine line positions - The animation uses a chain of transitions (one per line) with staggered timings - The stars are rendered using canvas, with SVG used for the paths - A two-stage particle system is used, first to write the text and then to explode it The example can be run locally or through the bl.ocks website. D3 is used for the text and path animations. Styling of the text includes a gradient background and the `text` is revealed by the star particles. The code is from a famous codepen, adapted to work as a block. --- **Please provide your description for the gallery (max. 120 words).** The audience is the visualization community, so you can use specialized terms.

This example animates a sequence of text lines, combining letter rotation with particle-based star bursts. The text is rendered as `<h1>` elements, with each letter wrapped in a `<span>` and colored individually. Using D3 v5, the animation chains transitions: letters first rotate and fade in along SVG `<path>` elements, while star particles burst from the path endpoints via a canvas-based particle system. The background is dark, and the animation loops, with the final line triggering a new star effect. The visualization uses both SVG for the text paths and HTML/CSS for the text elements, with the starfield rendered on a canvas. Interactivity is minimal, as the focus is on the animated introduction effect, though a mouse listener can be enabled. The example is designed for Chrome and relies on the "Indie Flower" Google font. # Animated Intro with Bursting Stars This dynamic text animation combines rotating letters with particle-based star bursts. The visualization displays four staggered lines of text, where each line enters with a rotating letter animation before exploding into a shower of glowing star particles. **Visual Design:** - Each letter is wrapped in a `<span>` and individually colored using CSS classes (5-color cycle) - Text is rendered in the "Indie Flower" webfont, adding a playful handwritten feel - Stars are created with canvas-based particle systems using blur and contrast filters, with additive blending on a dark background **Animation Sequence:** 1. Text lines fade in sequentially, with letters rotating -720° and scaling from 0 to 1 2. Once all lines are displayed, a star field bursts along the text paths 3. A second starfield with a different texture takes over for the final visual effect **Technical implementation details:** - SVG paths are created along the baseline of each text line to guide the star particles - Star particles are spawned along these paths using `getPointAtLength()` - The visualization uses two star textures (white and colored) at different stages of the animation - Google Font "Indie Flower" is loaded via WebFont before starting the animation The code includes utilities like `createFrames` and an `App` class (stars.js) that handle canvas-based particle rendering with blur and contrast filters for a glowing effect. --- This is the updated code of [EE2dev's original block](https://bl.ocks.org/EE2dev/e01de51772be2cace280a8b6bae30800).

Those letters are colored individually and animated into place, either by rotation, by bursting outward, or by a combination of both. The animation is powered by D3 v5 transitions on the letter spans and a custom canvas-based particle system that creates the star bursts. The visualization is built with D3 v5 and renders to both SVG and canvas. Text lines are defined as arrays of strings and displayed with Google's Indie Flower font. The animation first rotates and scales letters into place, and then a star particle system bursts out from the text using a path-following technique. Star paths are created from the text lines' positions, and the animation is chained line by line. A second instance of the particle system is used for the final line to create a more dynamic effect. The stars are blurred and combined with the text using contrast and blend modes to give a luminous look. The gallery includes multiple variants of this animation, all based on text and stars. Variations include different text elements like `<h1>` and SVG `<textpath>`, animation types, and color gradients.# Stars An animated text intro that combines rotating letters with explosive star particle effects. Text elements are displayed as `<h1>` elements, with each letter wrapped in a span that can be individually styled and animated. The animation sequences through multiple lines of text, first rotating the letters into view, then bursting them with star particles. ## Visual Design The visualization uses white or gradient-colored text against a dark background (`#111111`), with each letter individually colored using a repeating color palette (`color-0` through `color-4`). Individual letters are wrapped in spans that rotate and scale into place, while canvas-based star particles (drawn with a star-shaped texture) burst outward along text paths. The composition combines both SVG for the text paths and canvas for the particle system, with blur and contrast filters creating glowing effects. ## Technique The core technique uses `d3.transition` with chained callbacks to sequence animations through multiple text elements. Each header is wrapped in spans, which are sequentially rotated into view. Then, `getPointAtLength()` samples points along the SVG text path, and the `app.spawn()` function emits star particles at those points. The stars are rendered on a canvas using an `App` class that creates a particle system, with blend modes for additive blending and blur/contrast filters to create a glowing star effect. The `WebFont` loader ensures the custom font is loaded before the animation starts, and the Google Font "Indie Flower" is used. The entire sequence is orchestrated using transitions and chained animations with different types of star bursts used. The first version creates a simple sequence of text. The second and third version also rotate the entire text element (transition from rotate(-720deg) to 0, and the second one also animates individual letters with a 3D rotation). The last two versions use SVG `<textpath>` with a gradient and can have a background image.

My second animation

Words fly in from the center, enlarge, then snap into a grid ordered by their size while transitioning colors across a rainbow scale. The animation repeatedly adds random words from a duplicated dataset and occasionally removes one, demonstrating D3's `.enter()` and `.transition()` chaining with SVG `text` elements. The `refresh` function handles the branching method calls needed because transitions do not return the original selection, using the Cairo-inspired word cloud layout with columns and row offsets.

This example demonstrates how D3 transitions make data joins easier to follow by animating the entry, update, and exit states of SVG text elements. It shows a sequence of randomly selected alphabet letters that change every 1.5 seconds, with entering letters sliding down from above, exiting letters dropping below, and updated letters gliding horizontally to their new positions. The code uses D3’s selection joins with key functions, `transition.attr` and `transition.style` to animate positions and opacity, and relies on SVG text elements rendered in a single group. The data is a shuffled subset of the alphabet, sorted and re-joined with each interval.

This example creates an animated typography intro where text lines ("Javascript", "meets", "deep learning", "with", "TensorFlow.js") are revealed sequentially. Each line is rendered as an `<h1>` element, while the final line is split into individually colored spans. The animation uses an SVG `<textPath>` to define a path for each header, and a starfield particle system (rendered on canvas with blur and contrast filters) bursts along these paths as the text fades in. The text transitions are staggered, with each line's star trail animating along its path in sequence, and the final line triggers a longer particle effect. The design uses the Google Font "Indie Flower" and a dark background, with each letter of the last line assigned a different color.
