Forked from Fork of Fork of ICE8 - Social Network Graph

This example builds a simple force-directed node-link diagram from a JSON dataset. The code uses D3's `d3.forceSimulation` with `forceLink`, `forceManyBody`, `forceCollide`, and `forceCenter` to simulate the layout, positioning nodes in a circular arrangement with drag interaction via `d3.drag`. An SVG `line` per link includes an arrowhead marker, and each node is a circle with a text label. Hovering a node changes its stroke color to green via the `focusNode` and `blurNode` handlers. All nodes share the same group value in the source data, and the visual output is rendered using the SVG `viewBox` scaling.

A force-directed graph depicts the organizational network of the Kenneth Rainin Foundation, with large colored nodes representing main departments like Coordinacion and Comercial, smaller child nodes for teams, and tiny leaf nodes. The visualization uses D3.js v6 with `forceSimulation`, `forceManyBody`, `forceLink`, and `forceCenter` to compute node positions. SVG circles and lines render the network, with drag interaction enabling manual repositioning. Node and link colors are defined in a separate palette, and node labels display department names.

Node Linked Diagram with Force Directed Layout

This example displays a node-link diagram using a force-directed layout, visualizing connections from the soc-firm-hi-tech network data repository. It renders purple circular nodes and black links in SVG with animation, where hovering enlarges a node and dragging repositions it. The code builds the simulation with `d3.forceSimulation`, applying `d3.forceManyBody` for repulsion, `d3.forceCenter` for centering, and `d3.forceLink` for edges, updating positions via a ticked handler.

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.

Untitled

This example shows a force-directed graph of interconnected nodes, where each node is a small circular glyph and links are drawn as thin, slightly curved lines. The graph uses an offline dataset stored as an array and relies on `d3.forceSimulation` with `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCenter` to compute layout, while `d3.drag` enables user interaction. The visualization is rendered to a Canvas 2D context, with each frame clearing and redrawing positions from the simulation’s tick events. Node colors and sizes are static, and the code does not include labels or tooltips.

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.

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`.

D3 v4 - force layout

This example demonstrates a force-directed graph layout using D3 v4's physical simulation API. The visualization shows 100 labeled nodes connected by random links, with node sizes varying between 8 and 28 pixels. The simulation applies multiple forces—link attraction, collision avoidance, many-body repulsion, and centering—to position the nodes dynamically. Dragging nodes with the mouse temporarily restarts the simulation with higher alpha, allowing interactive manipulation of the network. The code uses `d3.forceSimulation`, `d3.forceLink`, `d3.forceCollide`, `d3.forceManyBody`, and `d3.drag` to render SVG circles and lines, updating positions on each simulation tick.

Untitled

This example visualizes a force-directed network graph using the d3.v4 library. The code loads node and link data from a JSON file and positions the nodes through `d3.forceSimulation`, applying repulsion (`d3.forceManyBody`), link constraints (`d3.forceLink`), and centering forces. Rendered as an SVG, nodes are orange circles with black strokes, connected by green lines. Node labels are positioned relative to each circle's computed coordinates, and the animation runs continuously as the force simulation updates the layout.
