This example visualizes country GDP data as a force-directed bubble chart. Each circle represents a country, with its radius proportional to GDP (capped at a minimum size) and its color indicating continent, using d3.scaleOrdinal for categorical coloring. The layout is computed by d3.forceSimulation, combining d3.forceX, d3.forceY, d3.forceManyBody, and d3.forceCollide forces to cluster and repel the nodes. Users can drag circles via d3.drag, temporarily fixing their positions during interaction. The data comes from a CSV file, and the SVG circles are positioned on each simulation tick.

AI-generated description

This is a basic implementation of D3's force layout, a.k.a. d3-force, in version 4.

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.

Untitled

This visualization shows a force-directed bubble chart where each circle represents a country, with its size corresponding to GDP data loaded from a CSV file. The bubbles are color-coded by team and cluster toward the center of the screen. The code uses d3.forceSimulation with forceX, forceY, forceCenter, forceManyBody, and forceCollide to position the nodes, while d3.drag enables interactive dragging of individual circles. The SVG rendering fills each node with a color from a d3.scaleOrdinal palette, and the simulation updates circle positions on each tick.

fresh block

This visualization displays a force-directed bubble chart of per-capita GDP data from Gapminder for 100 countries. Each country appears as a circle whose size and color encode its GDP value, with a color scale interpolating from blue to orange. Circles repel and collide using `d3.forceSimulation`, `d3.forceManyBody`, and `d3.forceCollide`. A tooltip showing the country code and dollar amount appears on mouseover. The SVG is rendered with D3 v4.

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`.

Force Simulation with Voronoi Diagram

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.

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: Split Categorical

A force-directed network of circles, sized by GDP and colored by continent, settles into a clustered layout. A "Toggle Split" button triggers a categorical separation: the `d3.scalePoint` scale maps each continent to a distinct x-coordinate, and an additional `d3.forceX` pushes nodes toward their group’s position, with labels emphasizing the grouping. The simulation uses `d3.forceSimulation`, `d3.forceManyBody`, and `d3.forceY` to manage repulsion and centering.
