squares-around-circles

The animation shows a grid of small circles, each surrounded by four square outlines that continuously expand and rotate. The squares appear to “breathe,” pushing outward and then resetting in a cyclical loop, creating a pulsing, geometric pattern across the screen. The code uses D3.js with SVG paths, leveraging the `transition` and `attrTween` methods for smooth movement. Each square’s position and orientation are calculated from its center point and a side number, updated via functions like `pushLinesOut` and `pointToPath`. The data is generated procedurally, with no external dataset.

This animated SVG visualization, rendered with D3.js, explores how geometric forms can be generated through code. The page loads a script called `circle-lattice.js` that draws a grid of small, semitransparent red rectangles, each with a faint stroke trail that animates to show their movement or placement over time. The layout is minimal—a single heading "Scripts" above the canvas—and the emphasis is on the lattice of shapes as they are built and possibly repositioned, revealing structural patterns through the animation. The visualization uses D3's data-binding and SVG rendering to create a dynamic, generative composition.

rect-spiral

An animated grid of squares repeatedly collapses to points and expands into colored rectangles against a dark background. Each cycle, a new set of squares appears, and the staggered delays create a cascading effect as they grow to full size. The code uses D3.js, lodash, and custom d3-starterkit helpers, appending `rect` elements to an SVG and animating their `width`, `height`, `x`, and `y` attributes via `transition()`. The grid positions are derived from dividing the viewport into a matrix, and each square’s fill color is randomly generated.

A grid of small circles and hexagon-like arrangements of rounded orange rectangles animates in a staggered transition. The visualization generates a field of triangular tile motifs, where each tile contains three small circles and three rounded rectangles positioned at their edges. Initially, the rectangles and circles sit at the tile centers; after a delay, they rotate outward to the triangle’s midpoints. Using D3.js with SVG transitions, the code applies `translate` and `rotate` transforms to reposition elements, driven by trigonometric calculations for hexagon geometry. The rendering uses D3 selections and transitions, with data-bound groups and nested arrays to handle multiple coordinates.

Animated Arcs

Four concentric animated arcs rotate continuously around a central point, each with a distinct color and its own random start and end angles. The arcs periodically change their sweep length and position, creating a dynamic, looping visual rhythm. Built with D3 v4, the example uses SVG paths and `d3.interval` to trigger transitions, while `transition.attrTween` and `d3.interpolate` smoothly animate each arc’s angles. The code generates random data for four arcs with varying radii and colors, drawing them with the `d3.arc` shape generator.

This example generates a continuously evolving abstract animation by drawing Voronoi polygons in alternating black and white. It shows a recursive process where each polygon’s edges are traced with short, sequential line segments that slowly shrink the polygon’s boundary, creating a spiral-like contraction. The animation uses D3’s `d3.geom.voronoi()` with a clip extent to create the polygons from random points, and then employs Canvas 2D API calls like `beginPath`, `lineTo`, and `stroke` to draw each step. A queue (`queue.js`) schedules the drawing of each polygon, and the code alternates stroke colors (`#000` and `#fff`) after each full pass, repeating indefinitely.

Multiple SVGs

Three stacked SVG panels show parallel animated sequences of circles moving horizontally across colored backgrounds. Each SVG contains ten circles driven by an array of numeric values, with one panel displaying a static blue dot alongside an expanding green-outlined circle, while the other two panels animate yellow and red outlines using D3 v5 transitions. The example demonstrates creating multiple independent SVG containers via d3.select and append, applying staggered transition.attr calls with a two-second duration to position circles at calculated coordinates.

svg voroni spiral

This example shows a static Voronoi tessellation over a set of random points, with animated spiraling lines tracing each polygon’s edges in sequence. It uses D3’s `d3.geom.voronoi` to compute the polygons from 40 random vertices, clipping them to the SVG canvas, and renders them as SVG `<path>` elements. The animation repeatedly shifts a point along each polygon’s perimeter, drawing a new line segment between consecutive points using `setInterval` and updating the `d` attribute of appended paths. The code relies on D3 3.5.5 and custom helper libraries (`d3-jetpack` and `d3-starterkit`) for concise SVG manipulation, with the overall rendering purely vector-based in SVG.
