A black background hosts a yellow-and-blue bubble chart that continuously grows as new circles are added every 295 milliseconds. The visualization shows a force-directed packing layout where each new circle pushes existing ones aside to make room. The code uses d3.forceSimulation with forceX, forceY, forceLink, and forceCollide to compute positions, while d3.pack and d3.stratify generate the initial layout from random data. Circles transition smoothly via d3 transitions in SVG, with sizes scaled by a d3.scaleLinear function.

Cluster Force Layout IV

This example shows 200 circles grouped into 10 color-coded clusters, with node positions initialized using the d3.layout.pack circle-packing layout and then animated into a clustered force layout via d3.layout.force. The simulation applies a custom cluster function to pull same-color nodes together and a collide function using d3.geom.quadtree to resolve overlaps. Circles enter with a staggered radius transition via attrTween, and the force tick updates SVG circle positions. The data is generated randomly, with radii derived from a log distribution and clusters defined by a categorical color scale.

Fork of packedlayout

Three groups of colored circles separate into loose clusters as a D3 force simulation runs. The visualization uses `d3.forceSimulation` with `forceX` pulling nodes toward three distinct horizontal centers, `forceManyBody` for repulsion, and `forceCollide` to prevent overlap. Each of the 100 randomly sized nodes is assigned one of three categories and rendered as an SVG circle whose fill color matches that category. The simulation updates positions on every tick, redrawing the circles via a data join in `index.js`.

Untitled

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.

packedlayout

This example shows a force-directed layout of 100 circles, each assigned to one of three categories and attracted to a corresponding horizontal center. The circles collide with one another while a many-body charge force disperses them, creating a packed, clustered arrangement. The visualization uses d3.forceSimulation with forceManyBody, forceX, and forceCollide, rendering to an SVG via d3.select and join. Data is randomly generated, and colors (orange, lightblue, purple) encode category membership.

Expand and fill force (work in progress)

Five hundred colored circles cluster in a cloud, then slowly diffuse outward as a force simulation seeks lower-density regions. The visualization uses custom forces within d3.forceSimulation, including a grid force and a hexbin-based expand force that samples random hexagon rotations and pushes nodes toward emptier neighboring bins. Rendered on Canvas, the circles respond to mouse movement, with the first node pinned to the cursor and the simulation restarting on interaction. The code employs d3.hexbin to compute density weights and d3.forceCollide to prevent overlaps.

Force Transition

A force-directed simulation arranges 100 circles into two distinct clusters, which switch positions when a button is clicked. The chart also includes a quantitative x-axis, making the clusters' locations measurable. Built with D3 v4, it uses `d3.forceSimulation` with `d3.forceX`, `d3.forceY`, and `d3.forceCollide` forces; clicking toggles the strength of the two horizontal forces, causing the groups to slide and swap sides. The simulation is rendered as SVG and animated on each tick, with the source code compiled from ES6 using the Babel browser library.

Basic Circle Pack

A hierarchical circle-packing visualization displays nested data as clustered bubbles, with zooming and panning via mouse clicks. The demo uses D3.js v5 to construct the SVG layout, apply an HSL color scale by depth, and animate transitions between hierarchy levels using `transition` and `interpolateZoom`. Buttons add or remove data nodes, while the pack layout is generated with `d3.pack` and `d3.hierarchy`. The dataset is hardcoded from a “flare” file structure.

Bubbles - Force bounding

This example demonstrates a force-directed bubble chart that packs 21 data values into a square boundary. Fixed "boundary" nodes, positioned along the top and left edges, constrain the visible data circles within the 500x500 pixel area. The visualization uses D3 v5’s `d3.forceSimulation`, combining `forceX`, `forceY`, `forceManyBody`, and `forceCollide` to repel and pack circles without overlap, while radii are scaled with `scaleSqrt`. Each bubble is rendered as an SVG circle with a white label. The simulation runs 120 ticks before rendering, and the final layout is drawn in a single frame.
