A clustered force layout renders 20 circles in four color-coded groups, with each group clustering around its largest member. The simulation uses a custom `cluster` force to pull nodes toward their group's anchor and a `collide` force with a quadtree to prevent overlapping circles. Built with D3 v3's `d3.layout.force`, circles are drawn as SVG elements with positions updated on each tick event. Custom gravity applies only to the largest node of each cluster, while other nodes repel based on inter-cluster padding.

AI-generated description

This clustered force layout is implemented using two custom forces. The first, cluster, pushes nodes towards the largest node of the same color. A second collide force prevents circles from overlapping by detecting collisions.

This example uses custom gravity applied only to the largest node of each color; compare to standard gravity.

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.

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.

Clustered Force Layout 4.0

This example shows a force-directed layout with 200 circles organized into 10 distinct clusters, each rendered in a different color from the `d3.schemeCategory20` palette. The circles are separated into their groups by the `clustering` custom force, while the `collide` function, which uses a quadtree, prevents overlap both within and between clusters. The visualization is built with D3 v4, uses the `d3.forceSimulation` API for physics, and renders via SVG. The `ticked` callback updates each circle’s `cx` and `cy` attributes as the simulation runs.

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.

Cluster Force Layout IV

This example shows a force-directed cluster layout where 200 nodes are grouped into 10 distinct color-coded clusters, with circle size representing varying radii. The visualization initializes node positions using D3’s circle-packing layout (`d3.layout.pack`) before transitioning to a custom force layout (`d3.layout.force`) that applies clustering and collision avoidance. During the animated tick, the `cluster` function pulls nodes toward their cluster’s largest node, while the `collide` function uses a quadtree (`d3.geom.quadtree`) to prevent overlap, separating nodes by padding or cluster padding based on cluster membership. The SVG circles are rendered with smooth entrance transitions via `transition.attrTween`, which interpolates radius from zero to their final value.

Clustered Force Layout III

This clustered force layout example shows a stable arrangement of colored nodes grouped into clusters, with one larger node per cluster and an animated transition from an initial state. The code uses D3 v3’s `d3.layout.force` with custom `cluster` and `collide` functions, initializing node positions in a circle to reduce jitter. It also applies a `transition.attrTween` to grow node radii smoothly, and renders labels alongside circles in SVG. The data is generated randomly, with cluster assignments and radii scaled via `d3.scale.sqrt`.

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.
