A force-directed graph with six colored nodes and three links demonstrates mapping link endpoints to node identifiers instead of numeric indices. The visualization loads graph.json, which stores node objects with id properties and links referencing those ids as source and target. D3's forceSimulation, forceLink with an id accessor, and forceManyBody position the SVG circles and lines. The code binds data to circle and line elements, sets fill colors from each node's id, and updates positions on every tick event.

This example shows how to link nodes in a force-directed graph using a named identifier rather than a numeric index.

29. Link Nodes by Name

Six colored nodes are linked by name rather than numeric index in this force-directed graph. The SVG renders circles and lines using d3.forceSimulation with d3.forceManyBody, d3.forceLink, and positional forces. Graph data from graph.json specifies node ids like "red" and "violet", and links reference those same ids as source and target. The simulation assigns coordinates, and the ticked function updates the circle centers and line endpoints accordingly.

D3 Node-Link Diagram

This example shows a node-link diagram of social network data, using a force-directed layout to position 16 nodes and their connecting links. The visualization uses D3 v7's `d3.forceSimulation` with `forceManyBody`, `forceLink`, and `forceCenter` to calculate the layout, while rendering nodes as SVG circles and edges as lines with animated tick updates. Node colors come from `d3.scaleOrdinal` with the `schemeSet1` palette, and hovering a node triggers a tooltip via mouseover events. Data is loaded from a CSV file containing source, target, and link values.

Graph Visualization

This example demonstrates a basic force-directed graph with three nodes connected by two links. The visualization uses D3’s `forceSimulation` with `forceManyBody` for repulsion and `forceLink` to define the edges, rendering nodes as SVG circles. The simulation updates node positions on each tick, which are applied to the circles’ `cx` and `cy` attributes. The data consists of a simple array of node IDs and link indices, drawn directly into an SVG container.

Force Directed Graph with markers and selectable links

This example demonstrates a force-directed graph where multiple links between the same pair of nodes are visually distinguished using colored strokes and arrowhead markers indicating direction. The graph uses `d3.forceSimulation` to position nodes and `d3.forceLink` to manage connections, with selectable links rendered as SVG paths that trigger click events. Node data and link descriptions come from JSON files, and labels are positioned along curved edge paths using `textPath` elements.

Untitled

This example presents a small force-directed network graph with six nodes labeled A through F and six weighted links. Node color is a uniform olive, while link thickness reflects the numeric “value” assigned to each connection. The underlying data, loaded from a JSON file, includes additional attributes like gender and occupation for each node, though these are not visually encoded. The visualization uses d3.forceSimulation with link, charge, and center forces, and supports interactive dragging. Node positions are updated on each tick, with SVG circles and text labels rendered through D3’s data join.

Diagram

This example shows a small directed graph with three labeled nodes and two links, laid out using a force-directed simulation. The nodes are rendered as circles with text labels, and the links are drawn as straight lines. The code uses `d3.forceSimulation` with `forceManyBody`, `forceLink`, and `forceCenter` to compute positions, and updates the SVG elements on each tick event. The data comes from a local JavaScript module with node and link arrays, and the visualization is rendered as SVG using React and D3 v6.

Force-Directed Graph

This is a force-directed graph visualization rendered as an SVG, showing three nodes and three links in a small network. The node and link positions are determined by a physical simulation where nodes repel each other and links pull connected nodes together. The code uses `d3.forceSimulation` to combine `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCenter` forces, updating SVG circle and line elements on each simulation tick. The data comes from a local JSON file with node IDs and link source/target references.

Node-Link Diagram

This node-link diagram visualizes a network of social firm connections using a force-directed layout. The code loads CSV data and creates circles for nodes and lines for links, with hover effects turning nodes red and displaying a tooltip label. It uses d3.forceSimulation with d3.forceLink, d3.forceManyBody, and d3.forceCenter to position elements, rendering the graph as an SVG with D3 v6.
