This example demonstrates custom radial forces in D3, positioning red nodes on a circle of radius 100 pixels and blue nodes on a radius of 200 pixels, with reference circles drawn as SVG paths. It uses `d3.forceSimulation` with a `d3.forceCollide` for node spacing and a `d3.forceRadial` force that targets each node’s radius based on its type. The simulation runs over a typed array of 240 nodes, and each tick updates circle elements’ `cx` and `cy` attributes. The visualization is rendered entirely in SVG with a `viewBox` centered at the origin.

AI-generated description

This example shows how to create a custom “radial” force that places nodes in a circle with a configurable radius and center. The red nodes form a circle of approximate radius 100px, and the blue nodes approximately 200px.

clusters force

This example shows 300 circular nodes grouped into three distinct clusters, each with its own radial gradient color scheme. The visualization uses a force-directed simulation with `d3.forceSimulation` and a custom cluster force to keep nodes near their group’s center, while `d3.forceCollide` prevents overlap by applying padding based on node radius. The nodes are drawn as SVG circles, with each cluster’s color derived from a linear scale mapped to a radial gradient, creating a smooth visual distinction. The code defines three separate radial gradients and assigns them based on the node’s cluster value, while the custom cluster force adjusts node positions relative to a designated cluster center.

D3 Force Simulation

This example shows a force-directed layout with 100 randomly connected nodes rendered as steelblue circles on an SVG canvas. The code creates nodes and links with random positions and connections using `d3.range` and `Math.random`. It uses `d3.select` to bind data and append circle elements with `attr` calls for positioning and styling. However, the simulation itself is not implemented—no `d3.forceSimulation` is invoked, so the graph remains static rather than animated. The visualization relies on D3 v4 and renders entirely via SVG.

D3 Force Simulation

This example shows a force-directed layout with 100 nodes and 100 randomly generated links rendered as circles and lines in an SVG. The code creates node positions using `Math.random()` and defines link source/target pairs randomly, but it does not run a force simulation or draw the links. It uses D3 v4 to bind data and append circle elements with a steelblue fill, sized at a radius of 3.5 pixels each.

D3 Force

This example demonstrates a simple force-directed simulation of three nodes (Alice, Bob, and Carol) connected by two links, rendered as circles inside an SVG element. The visualization uses D3’s `forceSimulation` API with `forceManyBody`, `forceLink`, and `forceCenter` forces, which are explicitly set up to model charge, link, and centering effects. The simulation’s `on('tick')` handler logs a message to the console, but the positions are not yet updated or drawn, so the visualization’s visible output is minimal. The code references the D3 library loaded via a CDN and selects the SVG container using `d3.select`.

D3 Force Simulation

This example displays a static force-directed network of 100 circles and 100 randomly generated links on an SVG canvas, using D3 v4. Nodes are positioned randomly and rendered as steelblue circles, while links are implied but never drawn, so the visualization focuses solely on node placement. The code prepares data structures for a force simulation but does not call d3.forceSimulation, leaving the layout in its initial random state.

D3 Force Simulation

This example shows a static scatterplot-style network diagram of 100 randomly generated nodes and links, rendered as steelblue circles on an SVG canvas. The code defines node positions and link endpoints using `d3.range` and `Math.random`, then appends circles via `svg.selectAll(".node").data().enter()`. Although the title suggests a force simulation, the visible code does not invoke `d3.forceSimulation`, leaving the layout fixed; the example relies on D3 v4 for data binding and SVG element creation.

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.

D3 Force Simulation

A force-directed network layout visualizes 100 nodes and 300 random links, rendered as circles and lines in an SVG canvas. The example uses D3 v4’s `d3.forceSimulation` with `forceCenter`, `forceManyBody`, `forceLink`, and `forceCollide` forces to compute positions. Nodes are draggable via `d3.drag`, which updates fixed positions (`fx`, `fy`) during interaction. The animation updates node coordinates and link endpoints on each simulation tick.
