This example presents a force-directed network graph of seven nodes representing a dean, two teachers, and four students, with weighted links showing relationships. The visualization uses D3 v4 and the older d3.layout.force API to position nodes within an SVG canvas. Node positions update dynamically via the force.on("tick") callback, while node dragging is enabled through force.drag. The graph reads its structure from a JSON file, rendering each node as a tomato-colored circle with a name label and links as stroked lines whose thickness corresponds to the link's weight attribute.

Network Graph

A network graph displays seven named nodes connected by weighted links, with node sizes and link thickness reflecting connection strength. The data, loaded from a JSON file, is rendered as an SVG using D3.js v4's force layout, which applies gravity, charge, and distance parameters to position nodes dynamically. Users can click and drag nodes to rearrange the network, while node labels and red-bordered yellow circles remain visible. The visualization uses `d3.layout.force` for simulation and `force.drag` for interactivity, with tick events updating link coordinates and node transforms.

Network Graph

A force-directed network graph displays seven named nodes connected by weighted links, with thicker strokes representing higher link weights. Nodes appear as red circles with blue outlines and black text labels, positioned through a simulated physical layout that responds to drag interactions. The visualization loads node and link data from a JSON file and uses the D3.js v4 library, specifically `d3.layout.force` for the simulation and SVG elements for rendering.

Network Graph

This network graph visualizes relationships among six people using a force-directed layout. It loads data from an external JSON file specifying nodes and weighted links, then renders nodes as orange circles with name labels and green lines for connections. The example uses D3 v4 and v2 APIs simultaneously, relying on `d3.layout.force` to simulate the physical forces that position the nodes. Link thickness scales with the square root of each connection’s weight, while a tick handler updates the SVG elements’ positions during the simulation.

Network Graph

A network graph displays six named nodes connected by six weighted links, with link thickness proportional to each connection’s weight. Using D3 v4’s force layout (`d3.layout.force`) and SVG rendering, the visualization positions nodes through simulated gravity, charge, and distance parameters. Node circles are blue with labels, and the layout updates continuously during the `tick` event to animate the graph. Data comes from a local `data.json` file containing node names, group assignments, and link weight values.

Social Network

The visualization displays a small social network of seven people, with weighted links indicating relationship strength. It uses a force-directed layout to position nodes, allowing users to click and drag them around the canvas. The graph is rendered as an SVG using D3.js, with brown strokes for links and silver circles with royal blue borders for nodes. Data comes from a local JSON file containing node names and link weights. The code relies on d3.layout.force() for the physics simulation, with node labels positioned to the right of each circle.

Network tree

This example shows a force-directed network tree with six nodes and five weighted links, rendered as draggable orange circles with text labels. The code uses d3.layout.force (v4) to simulate gravity, charge, and link distance, while rendering SVG lines and groups. Node weights set stroke-width via Math.sqrt(d.weight), and data loads from an external graphFile.json containing name, group, and link target/source arrays. The visualization updates node positions on each tick using the force layout’s tick event.

Graph Example

This example shows a force-directed network graph of 13 named nodes connected by 13 weighted links, with each node colored according to its assigned color property and labeled with its name. The visualization uses the D3.js v2 library, creating an SVG rendering that lays out the graph through the `d3.layout.force` API, positioning nodes with charge and distance settings. Links are drawn as lines whose stroke width scales with the square root of the link weight, and nodes are draggable circles with text labels. Data is loaded from the `graph.json` file, and the layout updates position coordinates on each tick event.

Network Graph

A force-directed network graph visualizes social connections among ten people, with labeled nodes and directed, arrowed links. Node size reflects connection strength through link thickness, and hovering highlights a node. The example uses D3 v6’s `d3.forceSimulation`, `d3.forceLink`, `d3.forceManyBody`, `d3.forceCollide`, and `d3.forceCenter` to position elements, rendering in SVG. Data comes from `graph.json` and includes relationship types and values. Interactive dragging is implemented via `d3.drag`.
