d3 | force grouping via events

This example demonstrates how d3-force can be used to group and ungroup data-driven circles through user interaction. Nine circles, colored by group (green for "one", orange for "two") and sized with a square-root scale, are simulated with forces for y-centering, centering, and collision avoidance. Clicking the SPLIT button swaps the x-force to push circles of group "one" toward x=200 and group "two" toward x=700, while JOIN returns all circles to the horizontal center. The simulation’s alphaTarget and restart methods smooth the transitions between the two layouts, and clicking a circle displays its name and value in the footer.

d3-force-cluster and d3-force-attract

Two hundred circles, shaded by cluster with a sequential rainbow scale, are positioned by a force simulation that combines `d3.forceAttract` to pull nodes toward the screen center and `d3.forceCluster` to group them into ten distinct clusters. The layout uses `d3.forceSimulation` with a custom `d3.forceCollide` whose strength ramps up over three seconds for a smooth transition. Each node is an SVG circle, rendered with `d3.drag` for interactive repositioning, while the tick handler updates the `cx`, `cy`, and `r` attributes. The data is generated randomly, with radii varying by cluster, and the example runs in the browser using D3 v4 and the `d3-force-attract` and `d3-force-cluster` plugins.

Clustered Force Layout I

This clustered force layout visualizes 200 circles organized into 10 color-coded clusters, with each circle’s size varying by cluster. The d3.v3 force layout uses two custom forces: a cluster force that pulls circles toward the largest node of the same color, and a collide force using d3.geom.quadtree to prevent overlaps. Circle separation differs between same-color and different-color pairs. The SVG rendering updates circle positions on each tick event, with colors assigned via d3.scale.category10.

Multi-Foci Force Layout

A multi-foci force layout clusters 100 circles into four groups using D3’s d3.layout.force with position Verlet integration. Custom forces push nodes up, down, and sideways based on their index, while d3.event and force.drag enable mouse interaction. Clicking the page perturbs node positions with random offsets, and the simulation resumes. SVG circles render with a categorical color scale and animate smoothly via the tick event.

Clustered Force Layout II

Ten clusters of colored circles drift and separate on a dark background, with each cluster gathering around its largest member while circles avoid overlapping. The visualization uses d3.layout.force with custom cluster and collide forces, leveraging d3.geom.quadtree for collision detection and d3.scale.category10 for colors. Data is procedurally generated in the browser, with 200 circles of varying radii across 10 groups, rendered as SVG elements.

Clustered Force Layout III

This example shows a clustered force layout where 200 circles are grouped into 10 color-coded clusters, with node sizes varying by cluster. D3’s force layout initializes nodes near their cluster’s center on a circular path, then applies custom cluster and collision forces during each tick to converge on a stable arrangement. An entry transition uses `transition.attrTween` to grow circle radii from zero, delaying collision detection to reduce jitter. The visualization is rendered as animated SVG using D3 v3, with data generated randomly via `Math.random` and `d3.scale.category10` for colors.

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.

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.
