A force-directed graph renders 15 numbered circles as colored nodes, each clipped to its Voronoi cell so the partition updates as nodes move. Users toggle between add and remove modes via a button; clicking a cell adds a new node at the cursor position, while clicking an existing node removes it. The layout uses d3.forceSimulation for physics, d3.voronoi for cell boundaries, and d3.drag for node interaction, with SVG elements for rendering and a color scale from d3.schemeCategory20.

AI-generated description

Created out of a SO question on force directed graphs with voronoi.

The layout includes:

  • Charged force layout,
  • Voronoi click based click events for dragging/removing, and
  • Dynamic adding/removing of nodes.

The voronoi updates with the force layout, based on:

Force Layout with Voronoi Cells and Add/Remove Node functionality

A force-directed graph renders colored nodes as Voronoi cells, with each cell clipped to a circular boundary and labeled by index. Users toggle between add and remove modes via a button, then click cells to dynamically insert or delete nodes, updating the layout in real time. The visualization uses d3.forceSimulation for physics, d3.voronoi to compute cell polygons, and d3.drag for node repositioning, with all elements drawn as SVG.

Force-Directed Layout with Convex Hull

This example shows 100 nodes grouped into nine clusters, each assigned a distinct color, with a Voronoi partition drawn over the simulated layout. The code uses d3.forceSimulation with forceX and forceY to position groups around a grid, plus d3.forceCollide to prevent overlaps, running 120 ticks before rendering. The Voronoi cells are computed with d3.voronoi and drawn as SVG paths, with a mouseenter effect that briefly highlights the corresponding cell in red. Nodes are rendered as circles using SVG, with links absent from the empty graph.

Force-Directed Layout with Convex Hull

This example shows a force-directed network with a Voronoi partition, where 100 nodes are grouped into 36 clusters and positioned through a physics simulation. The nodes are colored by group, and hovering over a Voronoi cell briefly highlights the corresponding node. The code uses d3.forceSimulation with x, y, charge, collide, and center forces, then runs 120 manual ticks. It renders SVG circles, lines, and Voronoi paths using d3.voronoi, with a single link connecting two nodes.

Force-Directed Layout with Convex Hull

This example demonstrates a force-directed layout where 100 nodes are organized into nine groups and arranged into a circular pattern using three columns. A Voronoi partition, generated with `d3.voronoi()`, divides the SVG canvas into polygonal cells around each node, with hover interactions highlighting the corresponding polygon in red. The simulation runs for 120 ticks via `d3.forceSimulation()` with forces for x/y positioning, collision avoidance, and centering, while nodes are rendered as colored circles with varying radii. The visualization uses SVG paths and circles, with the Voronoi cells drawn as white-filled polygons that react to mouse events.

Force-Directed Layout with Convex Hull

A force-directed network graph shows 100 colored nodes grouped into 30 clusters, linked by sparse connections and enclosed by a Voronoi partition that updates as nodes settle into position. The code runs 120 ticks of `d3.forceSimulation` with forces for links, charge, X/Y positioning, collision, and centering. Hovering a Voronoi cell highlights the enclosed node and its incident links. Rendering uses SVG circles, lines, and paths, with `d3.voronoi` computing the polygon boundaries over the simulated node coordinates.

Force-Directed Layout with Convex Hull

A force-directed layout places 100 randomly generated nodes into nine groups, each node with a random radius and connections to a few peers. The visualization displays these nodes as colored circles with black links, overlaid by a Voronoi diagram that partitions the canvas into convex hulls around each node. Hovering over a cell highlights it in red and briefly enlarges the corresponding node. The code uses `d3.forceSimulation` with force functions for links, many-body repulsion, positioning, collision, and centering, running 120 simulation ticks before rendering the Voronoi polygons and SVG elements.

Force-Directed Layout with Convex Hull

A force-directed network diagram positions 150 nodes into nine distinct groups, with each node colored by group membership. The visualization overlays a Voronoi tessellation—computed using `d3.voronoi`—on top of the node positions, creating clickable cells that highlight adjacent nodes and connected links on mouseover. Randomly generated links between nodes are drawn as black lines, and hovering a Voronoi cell temporarily dims unrelated links while emphasizing those touching the hovered node. The layout uses `d3.forceSimulation` with charge, position, and collision forces, running 200 ticks before rendering static SVG circles and paths.

Modifying a Force Layout with Voronoi Polygons for Dragging and Mouseover of Grouped Elements

This example demonstrates a D3 v4 force-directed graph whose three nodes can be dragged individually, while a Voronoi polygon behind each grouped element expands the clickable and hover area. Hovering activates a node's entire group, highlighting its circle and revealing its hidden text label. The simulation uses `d3.forceSimulation` with charge, link, and center forces, and recomputes the Voronoi overlay on every tick via `d3.voronoi`. The code dynamically adds and removes nodes and links on timed intervals using `d3.interval` and `d3.timeout`, updating the SVG paths, lines, and circles accordingly.
