A tiny SVG viewport shows 1,000 randomly placed circles bouncing and wrapping around its edges, with a live frames-per-second counter in the corner. The animation runs through `d3.timer`, updating each circle’s `cx` and `cy` attributes based on randomized velocity values. All rendering uses SVG elements and D3’s data join, with positions recalculated on every tick to keep the motion continuous.

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.

A cluster of 100 circles, each colored by one of four categories, moves under a force-directed layout in an animated SVG scene. D3's `d3.layout.force` continuously updates node positions, while a custom tick function applies directional offsets based on node index to separate groups into distinct clusters. Clicking or dragging any circle adds random jitter, causing the clusters to scatter and then re-form. The visualization uses D3 v3 with React, fading the entire SVG in over one second on load.

A vertical column of 50 circles animates across an SVG canvas, cycling horizontally in a loop. The circles are colored along a dark-to-light scale using `d3.scaleLinear` with HSL interpolation, creating subtle banding. D3 v4 selects the SVG, appends the circles, and chains `transition` calls with staggered `delay` and recursive `on("start", repeat)` to move each circle from left to right and back, demonstrating fundamental DOM manipulation and animation.

A constant stream of randomly generated scatter plots replaces itself every three seconds, with each frame plotting fifty circles at random coordinates, sizes, and colors. The visualization uses D3’s `select` and `join` methods to update circle and text elements in an SVG canvas. A static title and rotated axis labels accompany the shifting data, demonstrating dynamic data binding and animation via `setInterval`.

This visualization generates a dense packing of animated circles that grow from the center of an SVG canvas. Using a quadtree data structure to optimize collision detection, the algorithm iteratively places new circles in the largest available gaps, gradually increasing the number of candidate positions per circle. The code uses `d3.quadtree()` for spatial indexing and SVG `circle` elements with `transition()` animations to scale each circle's radius from zero. The process continues for 25,000 circles, with fill opacity randomly varied between 50% and 100%, creating an organically growing, space-filling composition.

Two circles move left to right across an SVG canvas, tracing a sine wave vertically as they travel. A black line connects their current positions, forming a dynamic segment that shifts with each animation frame. The visualization uses D3’s `select`, `range`, and `join` methods to update circle attributes, while `setInterval` drives the animation loop and a custom `drawLine` function appends and removes the connecting line. Randomly generated array manipulation is also present but unused in the final rendering.

Random Circles

Fifty randomly positioned and sized circles drift across the browser viewport in this d3.v6 example. Each circle's location updates on a timer, shifting by small random increments at every tick, creating a subtle Brownian-like motion. The visualization uses the `d3.range` function to generate the initial dataset, `d3.select` to create the SVG canvas, and the `d3.timer` API to drive the animation loop. Circles are styled as steelblue fills via CSS, with a light gray page background.

swirling circles

Hundreds of small, semi-transparent circles continuously stream inward from the top and bottom edges, converging at the center before dispersing outward again in a looping, decorative motion. The animation is generated entirely with D3 v3, using chained `transition()` calls over 2-second durations to animate each circle’s `cx` and `cy` attributes with a linear ease, then removing each element after its animation completes. Random colors are assigned via a custom `colorPicker` function, while circle starting positions and target offsets are determined by `Math.random()`. A `setInterval` spawns a new circle every 20 milliseconds, capped at 1,000 total per loop, which then repeats indefinitely.
