D3.force, multiple sets of multiple foci

Multi-Foci Force Layout

A multi-foci force layout clusters 100 circles into four groups using D3’s d3.layout.force with position Verlet integration. Custom forces push nodes up, down, and sideways based on their index, while d3.event and force.drag enable mouse interaction. Clicking the page perturbs node positions with random offsets, and the simulation resumes. SVG circles render with a categorical color scale and animate smoothly via the tick event.

Force-Directed Layout (Multiple Foci)

One hundred unconnected nodes in a D3 force-directed graph continuously move and cluster around four focal points. The layout uses custom forces that push even and odd indexed nodes in opposite vertical and horizontal directions, creating a structured pattern of four color-coded groups. Rendered as an animated SVG, the visualization relies on D3’s `d3.layout.force` with position Verlet integration, and a tick handler applies index-based directional pushes each frame. Clicking the page or dragging nodes perturbs their positions, which then resume the clustering behavior.

d3 | force grouping via events

This example demonstrates how d3-force can be used to group and ungroup data-driven circles through user interaction. Nine circles, colored by group (green for "one", orange for "two") and sized with a square-root scale, are simulated with forces for y-centering, centering, and collision avoidance. Clicking the SPLIT button swaps the x-force to push circles of group "one" toward x=200 and group "two" toward x=700, while JOIN returns all circles to the horizontal center. The simulation’s alphaTarget and restart methods smooth the transitions between the two layouts, and clicking a circle displays its name and value in the footer.

Multi-Foci Force Layout

Five fixed nodes serve as force foci that attract and repel moving nodes in a 2D space. As the mouse moves, the user spawns new nodes with random radii and colors; these nodes are pulled toward a focus matching their type while colliding with each other via a quadtree. The simulation runs on D3 v3’s force layout with custom attraction and collision logic, rendering everything as SVG circles with animated transitions that remove nodes after three seconds. The `d3.layout.force` API drives the physics, and `d3.geom.quadtree` accelerates collision detection.

Force Directed Graph

A force-directed graph shows the network structure of nodes and links, with each node colored by group and links weighted by value. Clicking a node highlights all connected links in red and simultaneously highlights the corresponding row and column in an adjacent adjacency matrix, where cell opacity reflects link weight. The implementation uses `d3.forceSimulation` with `forceLink`, `forceManyBody`, and `forceCenter`, renders nodes as SVG circles with drag and zoom support, and loads data from a `.edges` file.

Multi-Foci Force Layout

A stream of circles enters the scene at regular intervals, each assigned one of three focal points. The circles gravitate toward their assigned focus, creating three distinct clusters that shift as new nodes are added and older ones settle. Using D3 v3’s `d3.layout.force`, the example overrides the default tick handler to manually steer each node toward its focus, with the simulation’s alpha value controlling the easing. The SVG circles are colored via a categorical scale based on their focal point ID, and the animation runs indefinitely via `setInterval`.

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.

Multi-Foci Force Layout

A multi-foci force layout arranges 200 nodes into 10 distinct color-coded clusters, each pulled toward its own focal point along the horizontal axis. The visualization uses a custom gravity function to move nodes toward cluster centers and a collision detection routine built on a quadtree to prevent overlapping circles. Rendered as SVG with D3 v3, the code employs `d3.layout.force`, `d3.scale.ordinal` for focal positions, and `d3.geom.quadtree` for efficient proximity checks, with node radii derived from a logarithmic distribution.
