An interactive scatterplot maps national GDP and continent onto a force-directed layout of proportional circles. Each country is a node whose position balances simulated attraction, collision, and many-body repulsion forces, and a Voronoi diagram partitions the canvas into cells around the moving nodes. The visualization uses D3 v4’s `d3.forceSimulation`, `d3.forceManyBody`, `d3.forceCollide`, and `d3.voronoi` APIs, rendering SVG circles and paths. Users can drag nodes, which updates the simulation and recomputes the Voronoi tessellation in real time.

AI-generated description

This block uses D3 version 4's d3-force and d3-voronoi to compute the Voronoi diagram for a set of nodes in a force layout as they are dragged around.

For a simple demonstration of the Voronoi diagram, see this block.

For a version of this block without the Voronoi diagram, see this other block.

For more information on the various forces available in D3 v4, see Steve Haroz's d3-force testing ground.

Force Simulation

This force-directed layout shows the relative GDP of countries as node size, colored by continent, with a gentle pull toward the center. The simulation uses `d3.forceSimulation` with `d3.forceX`, `d3.forceY`, `d3.forceCenter`, `d3.forceManyBody`, and `d3.forceCollide` to position circles, which are rendered as SVG. The chart reads country data from a CSV file, sorts nodes so larger ones appear behind, and supports dragging circles to interactively perturb the layout.

D3-Force: Split Continuous

A force-directed graph of countries by GDP uses `d3.forceSimulation` with `d3.forceX` and `d3.forceManyBody` to position nodes on an SVG canvas. The "Toggle Split" button switches between a centered layout and one where nodes are pushed along a continuous linear scale mapping GDP values from left to right, with labels showing the domain endpoints. Data comes from a CSV file, and the simulation’s alpha and restart methods control the transition between states.

D3-Force: Split Categorical

This example visualizes GDP data for 15 countries, grouped by continent, as circles in a force-directed layout. A button toggles a categorical split, applying an invisible categorical axis so nodes align by continent using `d3.forceX` with a `d3.scalePoint` domain. The simulation uses `d3.forceSimulation` with `d3.forceManyBody` and centering forces, rendering to SVG circles and text labels. Data loads from a CSV via `d3.csv`.

D3 | Dorling map using force layout

This visualization shows a Dorling map where each country is represented as a circle positioned by longitude and latitude coordinates, with circle size encoding a numeric value and color a separate range value. A force-directed network layout adjusts the circles to avoid overlap, while an overlaid Voronoi grid enhances interactivity by providing stable hit areas for selecting countries. The map is built with D3 v3, using data from `dorling-coordinates.json` and `dorling-countries.json`, and the force simulation and Voronoi diagram are rendered via D3’s force layout and `d3.geom.voronoi` APIs. The Voronoi grid is visible in development mode but hidden in production.

D3-Force: Split Categorical

D3-Force: Split Categorical uses a force-directed simulation to show GDP by continent, with circles colored by GDP value. It displays how categorical grouping (continent) and continuous scaling (GDP) combine in an interactive layout. The code uses d3.forceSimulation with forceX and forceY to push nodes toward categorical and linear positions, while a button toggles between grouped and split states. It relies on d3.scalePoint and d3.scaleLinear for positioning, d3.scaleSequential with interpolatePiYG for color encoding, and transitions to animate the split. Data comes from a CSV file with country, continent, and GDP values.

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.

force directed test

A hierarchical dataset from a CSV file is visualized as a force-directed graph, where nodes are sized proportionally to a square-root-scaled `data` value and rendered as circular foreign objects containing wrapped text. SVG lines connect parent and child nodes based on the data's structure. The visualization uses D3 v4's `d3.stratify`, `d3.forceSimulation`, `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCollide` to position nodes, which are grouped elements containing a circle and an `foreignObject` with HTML content. The layout dynamically adjusts node positions and text fit during each simulation tick.

test

This example shows a force-directed scatterplot of country data, where each circle represents a country and its horizontal position reflects a chosen numeric measure (like per-capita values). Buttons let the user switch between linear and log scales, animating the circles to their new positions. The visualization uses `d3.forceSimulation` with `forceX`, `forceY`, and `forceCollide` to position the circles, while `scaleLinear` and `scaleLog` define the axes. Circles are colored by continent, and hovering reveals a tooltip with details, plus a dashed vertical guide line. Rendering is SVG with transitions.
