A force-directed layout uses D3's `d3.layout.force` to simulate repulsive and attractive forces among 200 circles, each with a random radius between 4 and 16 pixels. The root node is fixed at the center with a negative charge, pulling all other circles toward it while collision detection via `d3.geom.quadtree` keeps them from overlapping. As the simulation ticks, circle positions update in an SVG canvas, and users can drag the root node by moving the mouse, which resumes the force simulation to re-layout the surrounding nodes dynamically.

A force-directed layout uses a d3.geom.quadtree for collision detection among 200 circles of varying radii, with a fixed root node at the center. The root’s position follows the mouse via an SVG mousemove event, causing the simulation to resume and repel other nodes. Circles are rendered as SVG elements with colors from d3.scale.category10, and d3.layout.force manages gravity and charge between nodes.

This example shows a force-directed layout of 200 colored circles that repel each other and collide as they move. Dragging the mouse moves a fixed root node, pulling the surrounding circles toward the cursor. The visualization uses D3 v3’s `d3.layout.force` with custom gravity and charge functions, and a quadtree via `d3.geom.quadtree` to efficiently handle collision detection between circles. Each circle’s radius is randomly assigned, and its fill color comes from a categorical scale (`d3.scale.category10`). The rendering is done in SVG, with positions updated on each tick event.

A force-directed particle system in SVG uses D3 v3’s `d3.layout.force` to simulate 200 circles with random radii, while a fixed center node applies a strong negative charge to repel others. A quadtree (`d3.geom.quadtree`) accelerates collision detection, and the layout’s `on("tick")` event updates circle positions. Mouse movement drives the root node’s velocity via `d3.mouse`, resuming the simulation. The visualization runs in React, though the rendering logic is pure D3.

A force-directed graph of 100 nodes and 100 links arranges itself into a circular structure using d3.forceSimulation with charge, link, X, and Y forces. The layout is pre-computed by running the simulation to completion before rendering, then SVG circles and lines are drawn. The code uses D3 v4's forceSimulation API and React-ready SVG output.

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.

An interactive force-directed graph lets users create nodes by clicking, with new nodes automatically linking to any existing nodes within a 30-pixel radius. The visualization uses d3.layout.force for physics simulation, SVG circles for nodes, and lines for links, rendered in a React-free vanilla HTML page with d3.v3. A brown cursor circle tracks the mouse, and nodes are draggable via force.drag.

This example shows 100 unlabeled circular nodes clustering into four groups through a force-directed layout. The nodes are pushed in different directions based on their index, creating a visual separation of categories while the simulation runs. The visualization uses the D3.js v3 force layout with custom tick logic to apply directional forces, and renders the nodes as SVG circles with categorical colors from `d3.scale.category10()`. Clicking the background applies random jitter to all nodes and resumes the force simulation, while dragging individual nodes is supported via `force.drag`. A fade-in transition animates the SVG’s opacity on load.

This example uses D3.js to simulate a force-directed graph, visualizing the relationships between nodes as they settle into a stable layout. The code employs `d3.forceSimulation` with charge, link, and centering forces to animate the network, while the nodes are rendered as circles on an SVG canvas using `d3.drag` for interactivity. The graph’s data is generated locally within the script, producing a dynamic, physics-based visualization. The layout adapts in real time as forces push and pull connected elements, highlighting the underlying network structure through motion and proximity.
