A force-directed graph of 100 nodes and their links is projected onto a sphere using D3 v3’s `d3.geo.path` and a selectable geo projection (e.g., orthographic, mercator). The force layout positions nodes in 3D spherical space, and the SVG paths render the resulting network, with node colors from a categorical scale. A dat.GUI panel lets users switch projections, toggle clipping, and adjust force parameters like link distance and charge. Dragging rotates the projection instead of moving nodes.

Spherical Force-Directed Layout

This example shows a force-directed graph whose nodes and links are wrapped onto a sphere, with the sphere’s rotation controlled by drag. The layout uses D3’s force simulation (`d3.layout.force`) to position nodes, while each node and link is rendered as an SVG path transformed by a geo projection (`d3.geo.path`). The interface, built with dat.GUI, lets users switch among projections (e.g., Orthographic, Mercator) and adjust force parameters (link strength, distance, gravity) in real time.

D3 force layout

A force-directed graph layout shows a network of 26 named nodes connected by 11 links, with each node displayed as a GitHub favicon icon and a text label. The visualization uses D3 v3’s `d3.layout.force` to simulate physical forces with zero gravity, a charge of -2, and a link distance of 100, while the simulation updates node positions and link coordinates on each tick event. Data is loaded from a local `graph.json` file containing node groups and link betweenness values, and the SVG rendering includes draggable nodes and grey lines for links.

D3 v4 - force layout

This example demonstrates a force-directed network layout of 100 nodes and 100 links, rendered as animated SVG circles and lines. The visualization uses d3.forceSimulation with forces for link attraction, collision detection, many-body repulsion, centering, and x/y positioning. Users can drag nodes within the 900×500 pixel graph area, with the simulation’s alpha target adjusting during interaction. The layout updates every tick, repositioning nodes and links based on the simulation state.

D3: Force layout

A force-directed network graph displays ten named nodes connected by thirteen edges, with each node rendered as a colored circle and edges as gray lines. The simulation uses the D3 v3 `d3.layout.force` API, configured with a link distance of 50 and a charge of -100, to position nodes dynamically within a 500 by 300 pixel SVG canvas. Node colors come from `d3.scale.category10()`, and drag interaction is enabled via `force.drag`. The visualization updates on each tick of the force simulation, which adjusts node coordinates and redraws the SVG elements accordingly.

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.

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.

Force-Directed Graph

A force-directed graph displays 13 nodes and 18 links, using a physical simulation to position the circles and lines in an organic, interconnected layout. The D3 v3 code constructs an SVG scene with `d3.layout.force`, applying a negative charge to repel nodes and a tick handler to update the `x`, `y`, `cx`, and `cy` attributes of the line and circle elements. The graph’s structure is defined by a hard-coded nodes array and links array, representing an abstract network for the visualization.

D3 v4 - force layout

This example shows a force-directed graph with 100 randomly generated nodes and links, rendered as SVG circles and lines. The code builds the network using `d3.forceSimulation` with forces for link distance, collision, charge, centering, and X/Y positioning, then updates node and link positions on each tick. Nodes are draggable via `d3.drag`, and drag events adjust the simulation’s alpha target to restart or settle movement. The data is synthesized in the script, and the visualization initializes from a blockbuilder.org fork.
