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.

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.

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 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.

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`.

Clustered Force Layout I

This clustered force layout visualizes 200 circles organized into 10 color-coded clusters, with each circle’s size varying by cluster. The d3.v3 force layout uses two custom forces: a cluster force that pulls circles toward the largest node of the same color, and a collide force using d3.geom.quadtree to prevent overlaps. Circle separation differs between same-color and different-color pairs. The SVG rendering updates circle positions on each tick event, with colors assigned via d3.scale.category10.

Grid Multi Foci Force Layout

This example shows a grid multi-foci force layout that clusters circles representing project statuses and owners. Each node is colored by a categorical scale and positioned near one of several fixed focal points arranged in a grid, with node radius encoding a numeric value. The visualization uses D3 v3’s force layout to simulate attraction toward these foci, with an ordinal x-scale mapping statuses to columns. Data is drawn from an inline JavaScript array, and rendering is done via SVG circles with jQuery used for window sizing.

Clustered Force Layout II

Ten clusters of colored circles drift and separate on a dark background, with each cluster gathering around its largest member while circles avoid overlapping. The visualization uses d3.layout.force with custom cluster and collide forces, leveraging d3.geom.quadtree for collision detection and d3.scale.category10 for colors. Data is procedurally generated in the browser, with 200 circles of varying radii across 10 groups, rendered as SVG elements.

Cluster Force Layout IV

This example shows a force-directed cluster layout where 200 nodes are grouped into 10 distinct color-coded clusters, with circle size representing varying radii. The visualization initializes node positions using D3’s circle-packing layout (`d3.layout.pack`) before transitioning to a custom force layout (`d3.layout.force`) that applies clustering and collision avoidance. During the animated tick, the `cluster` function pulls nodes toward their cluster’s largest node, while the `collide` function uses a quadtree (`d3.geom.quadtree`) to prevent overlap, separating nodes by padding or cluster padding based on cluster membership. The SVG circles are rendered with smooth entrance transitions via `transition.attrTween`, which interpolates radius from zero to their final value.
