circle

A single red circle rendered in SVG, centered within a full-viewport canvas, with a green radial line extending from its center to the right edge. The visualization demonstrates basic D3.js v6 setup and styling, using inline SVG elements and a CSS hover animation that rotates the entire group containing both shapes. The code defines a `g` element with an id, positions it via a CSS transform, and applies a keyframe animation on hover that spins the group 360 degrees over five seconds. No data is loaded; the example focuses purely on static geometric primitives and interactive CSS-driven motion within an SVG coordinate system.

stroke dash gap

Five white circles with black outlines demonstrate the visual effect of decreasing stroke-dasharray values, from 30,30 to 1,1, which creates progressively finer dash-and-gap patterns along each circumference. Rendered as static SVG shapes using d3 v5, the example calls d3.select to append circle elements and sets their stroke, stroke-width, and stroke-dasharray attributes directly. The textures library is included but unused in the visible code.

stroke dash gap

Five circles of decreasing radius demonstrate how the stroke dash gap scales with size, using line textures as fill patterns. The example uses the textures library’s `textures.lines()` method with varying `size` parameters (from default to 10, 5, 3, and 2) to create vertical line patterns. Each circle is rendered as an SVG element with D3 v5, applying the texture URL via `.style("fill", t.url())` while maintaining a black stroke outline. The visualization highlights how pattern density changes relative to circle dimensions.

Circles with D3

Seven circles of varying sizes and colors float on a muted pink background. The visualization demonstrates static circle generation using D3 v7, with each circle’s position, radius, and fill color defined in a hardcoded array. The code uses `select`, `join`, and attribute setters like `.attr('cx')` and `.attr('r')` to render the shapes. A fixed opacity of 0.63 is applied uniformly, and the SVG resizes to its container dimensions.

Circles

A set of 40 concentric circles radiates from the center of an SVG canvas, each stroke drawn in solid red with 50% opacity and a 10-pixel width. The circles grow from a minimum radius of 20 to a maximum of 80, incrementing linearly, while the outermost circle reaches a radius of 300. Rendered using React’s `ReactDOM.render` into a `div` root, the visualization maps an array of radii to `<circle>` elements, with the SVG dimensions fixed at 960 by 500 pixels. The code explicitly computes radius values in a loop, though the final array contains a single undefined element.

Circles

A field of 1,000 small circles drifts randomly across an SVG canvas, wrapping around the edges when they exit the viewport. A text label in the corner displays a live frames-per-second counter. The animation uses `d3.timer` to update each circle's `cx` and `cy` attributes every frame, with positions stored in a data array generated from `d3.range(1000)` and `Math.random`. The code runs on D3 v3 and renders purely with SVG elements.

circles

Three concentric circles rotate continuously around a shared center, with red and green fills determined by radius and blue radial lines indicating rotation. The visualization uses D3 version 6 to append SVG `circle` and `line` elements inside `g` groups, updating their `transform` style via a JavaScript `setInterval` timer. A CSS `@keyframes` animation on hover triggers an additional 360-degree rotation. The code demonstrates D3’s declarative selection and merging API with `d3.select`, `enter`, and `merge` on an SVG canvas sized to viewport dimensions.

D3 Circle animation

Eight red circles animate simultaneously along straight paths within a large circular outline on a white background. Each circle travels from a point on the circle’s perimeter toward the center, with staggered start times creating a rotating, pulsing effect. The animation uses SVG’s `animateMotion` element with the `path` attribute and staggered `begin` times, while the overall layout and styling come from static SVG markup with `mix-blend-mode: hard-light`. The example relies solely on native SVG animation, not D3’s JavaScript APIs.
