A force-directed simulation of 2,000 nodes drifts across a canvas while a contour density field, computed via `d3.contourDensity`, is redrawn each tick with `d3.geoPath`. The contour thresholds increase over time, causing the filled regions to shrink and eventually vanish as the simulation settles. The color cycles through a steelblue-to-orange scale using a linear interpolator, and the canvas context directly handles all rendering. The example demonstrates how dynamic thresholds and a decaying force layout produce a gradually drying-up visual effect.

AI-generated description

A deviation of this. Visualization will end/dry up as the contour density threshold increases past the maximum density of the force nodes - leading to some neat final results.

Gooey Force Layout N-body Problem with Contours

Five hundred unattached nodes drift in a perpetual N-body force simulation, their positions continuously recomputed by d3.forceSimulation with charge and center forces. As the nodes move, a d3.contourDensity estimate generates contour paths from their current coordinates, rendered as filled SVG paths via d3.geoPath. The contours are colored with a sequential YlGnBu scale, producing a gooey, fluid-like visualization of point density that updates on every tick.

Gooey Force Layout N-body Problem - Canvas

This example shows a gooey, blob-like visualization of 400 nodes simulated with an N-body force layout, rendered on a Canvas element. The simulation uses `d3.forceSimulation` with a `forceManyBody` charge and no velocity decay, causing the nodes to move continuously. Each frame, `d3.contourDensity` computes density contours from the node positions, and `d3.geoPath` draws the filled and stroked contour shape, creating a smooth, merged form. The code uses D3 v4 and the d3-contour and d3-scale-chromatic libraries.

Force Layout with Canvas

This example shows a force-directed graph rendered on a canvas element instead of in SVG, using d3.layout.force to compute the layout and the Canvas 2D API’s `getContext` and `arc` for drawing. The graph loads node and link data from a local `graph.json` file, with nodes drawn as steelblue circles and links as gray lines. The simulation runs continuously, updating the canvas on each tick event by clearing the frame and redrawing the nodes and links. Unlike the SVG version, nodes are not draggable, but the canvas approach offers modest performance improvements.

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.

D3 Force Simulation

This example shows a force-directed layout with 100 randomly connected nodes rendered as steelblue circles on an SVG canvas. The code creates nodes and links with random positions and connections using `d3.range` and `Math.random`. It uses `d3.select` to bind data and append circle elements with `attr` calls for positioning and styling. However, the simulation itself is not implemented—no `d3.forceSimulation` is invoked, so the graph remains static rather than animated. The visualization relies on D3 v4 and renders entirely via SVG.

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.

Expand and fill force (work in progress)

Five hundred colored circles cluster in a cloud, then slowly diffuse outward as a force simulation seeks lower-density regions. The visualization uses custom forces within d3.forceSimulation, including a grid force and a hexbin-based expand force that samples random hexagon rotations and pushes nodes toward emptier neighboring bins. Rendered on Canvas, the circles respond to mouse movement, with the first node pinned to the cursor and the simulation restarting on interaction. The code employs d3.hexbin to compute density weights and d3.forceCollide to prevent overlaps.

Force-Directed Tree

A force-directed tree renders 1,000 procedurally generated nodes connected in a hierarchical link pattern, with a force simulation continuously repositioning them. The code uses `d3.forceSimulation` with charge, link, x, and y forces to drive the layout, while drawing to a Canvas 2D context. Nodes appear as small filled circles, and links are stroked lines in gray, with the entire scene offset to the canvas center. Interactive dragging is enabled via `d3.drag`, letting users pull any node and observe the layout rebalance in real time.
