This example shows a force-directed graph rendered on a canvas element instead of in SVG, using d3.layout.force to compute the layout and the Canvas 2D API’s `getContext` and `arc` for drawing. The graph loads node and link data from a local `graph.json` file, with nodes drawn as steelblue circles and links as gray lines. The simulation runs continuously, updating the canvas on each tick event by clearing the frame and redrawing the nodes and links. Unlike the SVG version, nodes are not draggable, but the canvas approach offers modest performance improvements.

AI-generated description

This example demonstrates rendering a D3 force-directed graph using Canvas rather than SVG. The performance is slightly better than SVG, but unlike the SVG version, the nodes in this one are not draggable.

Force Layout from Adjacency List

This example demonstrates a force-directed graph layout using data from a JSON adjacency list. Nodes are rendered as circles and edges as lines in an SVG canvas. The layout physics, including collision detection and link constraints, are handled by the `d3.layout.force` API, while node dragging is enabled via `force.drag`. The graph is initialized from the `graph.json` file, which defines connections between 24 numbered nodes, and the simulation updates node and link positions on each tick.

Force layout on canvas with zoom/pan and drag

A black canvas displays a force-directed network of small white nodes with red exceptions, connected by white edges. The example uses D3 v4 and d3-force v1, with d3.forceSimulation managing the layout. Users can pan, zoom, and drag nodes via d3.zoom and d3.drag, with all rendering performed directly on the canvas 2D context. Node positions update on each simulation tick, and the graph is drawn from a local data.json file.

Force layout on canvas with zoom/pan and drag

A force-directed network layout renders nodes and edges on a canvas with zoom, pan, and drag interactions. The visualization uses `d3.forceSimulation` to position nodes based on charge, link, and centering forces, while `d3.zoom` and `d3.drag` handle transformations and node fixation. Data comes from a local `data.json` file containing node IDs and links. Nodes are drawn as circles, with one node colored red via a custom `col` property, on a black background.

Fork of Canvas Force Tutorial

This example shows a force-directed network graph rendered on a Canvas element using d3 v5. Nodes and links are drawn as circles and straight lines, positioned by a d3.forceSimulation with forceX, forceY, forceCollide, forceManyBody, and forceLink forces. The graph loads its edge list from a CSV file (data.csv), which contains source, target, and weight fields, and updates the visualization on each simulation tick via the canvas 2D context.

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.

How to D3 Force Directed Layout Graph

This example demonstrates a force-directed layout graph using D3.js (v5). Nodes and links are rendered as SVG elements, with the graph's structure implied by the bundled JavaScript. The code uses D3’s built-in force simulation (d3.forceSimulation) to position the connected nodes naturally, while the stylesheet defines the visual appearance of the nodes as grey circles and the links as grey lines. The data is not explicitly shown, but the layout emerges from the simulated forces between connected nodes.

Fork of Canvas Force Tutorial

This example visualizes a force-directed network of people and their weighted connections. It uses D3 v5’s `d3.forceSimulation` with `forceLink`, `forceX`, `forceY`, `forceCollide`, and `forceManyBody` to position nodes, and renders the graph on a Canvas element via the 2D context’s `arc`, `moveTo`, and `lineTo` methods. Data is loaded from a CSV file specifying source, target, and weight. The simulation updates the drawing on each tick, producing an animated, interactive layout.

Fork of Canvas Force Tutorial

This example shows a force-directed network visualization rendered on a 500×500 HTML canvas. Nodes and links are loaded from a CSV file and positioned using d3.forceSimulation, with forces for X/Y centering, collision, charge, and link constraints. The simulation updates on each tick, clearing and redrawing the canvas with simple circles and connecting lines. It uses D3 v5’s force functions and Canvas 2D context for drawing.
