D3 Force Directed Graph

D3 Force Simulation

A force-directed network visualization shows 100 nodes and 300 random links in a 400-by-400 SVG canvas. The layout uses D3 v4’s `d3.forceSimulation` with `forceCenter`, `forceManyBody`, `forceLink`, and `forceCollide` to position and repel elements. Nodes render as steelblue circles, links as gray lines, and drag behavior lets users reposition nodes through `d3.drag`. The simulation updates node and link coordinates on every tick via the `ticked` function.

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.

Force Directed Graph

This visualization employs a force-directed graph to display a dataset of 410 linked nodes, loaded from a TSV file. The d3-force simulation, using `forceSimulation`, `forceLink`, and `forceManyBody`, positions the nodes with link thickness proportional to edge weight. Nodes are colored by a group value, and interactive dragging with `d3.drag` and zooming with `d3.zoom` are enabled. A separate, non-interactive adjacency matrix, built with `d3.select` and `reorder`, is shown but not linked to the graph.

D3 Force-Directed Graph

This example demonstrates a force-directed network layout, visualizing a small set of nodes and their connections with interactive dragging. The graph dynamically arranges connected circles using a physics simulation, cleanly separating linked nodes while repelling them from one another. The visualization is built with D3 v7, using `d3.forceSimulation` together with its `forceLink`, `forceManyBody`, and `forceCenter` components. The SVG output renders nodes as circles with labels and edges as straight lines, with positions updated on each simulation tick. The code also includes a guard that filters out any edges referencing non-existent nodes, ensuring the structure remains valid.

D3 Force Simulation

A force-directed network of 100 nodes and 300 randomly generated links settles into a stable layout under a centering force, many-body repulsion, link distance constraints, and collision avoidance. The visualization uses D3 v4's `d3.forceSimulation` with `d3.forceCenter`, `d3.forceManyBody`, `d3.forceLink`, and `d3.forceCollide` to animate the physics, while nodes are draggable via D3's drag interaction. The simulation updates an SVG canvas on each tick, redrawing lines and circles as positions change. The random data is generated programmatically, creating an abstract, interactive demonstration of force-based layout.

Force Network

This example demonstrates a force-directed network graph with draggable nodes connected by arrowed links. The visualization uses D3.js v6’s `d3.forceSimulation`, combining `forceLink`, `forceManyBody`, `forceCollide`, and `forceCenter` to position nodes. Nodes are colored by group, with hover highlighting via CSS classes, and SVG markers render arrowheads. Data comes from an external `data.json` file, loaded asynchronously with `d3.json`.

Force Directed Graph

A force-directed graph displays a network of 410 nodes and their connections, with node colors assigned by group via `d3.schemeCategory10`. The visualization pairs the graph with an adjacency matrix rendered as SVG rectangles, where users can click either nodes or grid cells to highlight corresponding links and matrix positions. Built with `d3.forceSimulation`, `forceLink`, `forceManyBody`, and `forceCenter`, the graph supports drag-and-drop node repositioning and zoom/pan interactions through `d3.zoom`. The adjacency matrix uses `d3.select` to update stroke and fill opacity based on edge weights.

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.
