Force-Directed Symbols

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.

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 Force Simulation

This example shows a force-directed layout with 100 nodes and 100 randomly generated links rendered as circles and lines in an SVG. The code creates node positions using `Math.random()` and defines link source/target pairs randomly, but it does not run a force simulation or draw the links. It uses D3 v4 to bind data and append circle elements with a steelblue fill, sized at a radius of 3.5 pixels each.

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.

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.

Sticky Force Layout

D3’s force layout runs with 13 nodes and 18 links from `graph.json`, rendered as SVG circles and lines. Dragging a node during the layout’s drag behavior sets its `fixed` property to true on `dragstart`, preventing the simulation from moving it afterward; double-clicking clears that flag. The force layout automatically resumes on `dragmove`, so the repositioned node continues to affect neighbors. Fixed nodes turn red, and the code uses `d3.layout.force`, the drag behavior, and explicit `tick` handlers to update positions.

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.
