This example uses D3 v4’s force simulation to create a draggable, distorted map of the lower 48 U.S. states. It first draws the state boundaries as SVG paths using `d3.geoPath` and TopoJSON data from `us-10m.v1.json`, then computes state centroids and connects neighboring states via a Voronoi tessellation (`d3.voronoi`). The simulation applies `d3.forceManyBody`, `d3.forceLink`, and `d3.forceCenter` to let users pull states apart while maintaining link distances. The view shows the map’s shapes and links shifting dynamically as the simulation runs, with drag interactions handled by `d3.drag`.

Force-Directed States of America

A force-directed graph rearranges the lower 48 U.S. states using links derived from a Delaunay triangulation of their centroids. Gray state polygons and connecting lines render in SVG, with the layout computed by `d3.layout.force`. The code loads TopoJSON data via `d3.json` and uses `d3.geo.path` to project state shapes. Users can click and drag any state, causing the simulation to re-position the linked nodes dynamically.

Force-Directed States of America

This interactive visualization displays the lower 48 U.S. states as a force-directed graph. Each state is a filled polygon node, and the links connecting them are derived from the Delaunay triangulation of state centroids. Users can click and drag states to rearrange the map, with the layout physics responding in real time. The code uses D3 v3 with the `d3.layout.force` API for simulation, `d3.geo.path` for rendering state shapes, and `d3.geom.voronoi` to compute the links. The map data comes from a JSON file of U.S. states, with Alaska, Hawaii, and Puerto Rico excluded.

This example uses D3.js v3 and TopoJSON to render a force-directed layout of U.S. state centroids, with Voronoi links connecting neighboring states. The code loads a U.S. map from a JSON file, filters out non-continental states, and computes centroids via `d3.geo.path().centroid()`. A `d3.layout.force()` simulation positions the nodes while maintaining link distances derived from the Voronoi cells. SVG paths draw each state’s shape, and lines represent the Voronoi links, updating on each tick. The visualization highlights geographic adjacency through network topology rather than choropleth coloring.

D3 + Leaflet

This example combines D3.js and Leaflet to create an interactive map of U.S. states with a hover effect. It uses a Leaflet tile layer from OpenStreetMap as the base, with D3 rendering state boundaries as SVG paths overlaid on the map. The code loads GeoJSON data from a gist and projects it using a custom `d3.geo.transform` that converts coordinates to Leaflet’s layer points. The `d3.geo.path` draws the states, and hover fills them brown. The map’s `viewreset` event triggers a reset function to reposition and rescale the SVG overlay.

Let's make an interactive US Map with D3.js!

An interactive SVG map of the United States renders state boundaries with basic hover styling. Using the D3.js and TopoJSON libraries, it loads a `states-10m.json` TopoJSON file, converts the topology into GeoJSON features, and projects them with an Albers equal-area conic projection via `d3.geoAlbersUsa()`. A zoom interaction updates the map's SVG transform, while each state path gains a tooltip showing its name.

Untitled

This interactive map of the United States uses a D3.js geographic projection to display state boundaries, rendered as SVG paths from TopoJSON data. Clicking a state zooms in via a smooth `transition` that adjusts the group’s scale and translate attributes, while the clicked state is highlighted in orange. A click on the background resets the view, returning the map to its original scale and stroke width. The example relies on `d3.geo.albersUsa`, `d3.geo.path`, and TopoJSON’s `feature` and `mesh` methods.

Let's make a US map with D3.js!

This example demonstrates how to create a map of the United States using D3.js, rendering each state as a green SVG path with black strokes. The code loads county-level TopoJSON data from the us-atlas package, extracts state boundaries with topojson.feature, and projects them using the d3.geoAlbersUsa() projection. State paths are generated with d3.geoPath and appended to an SVG element, with styles defined in an accompanying CSS file. The example uses D3 v5 and relies on the geo-albers-usa-territories plugin for the projection.

This example visualizes U.S. state boundaries using D3 v4’s geoAlbersUsa projection and d3.geoPath to render geographic features from a local us-states.json file. The SVG canvas, sized 700x580, is appended to the body, and each state’s polygon is drawn as a path element with a default fill and stroke. The map is centered using a translate of [width/2, height/2], and the simple code demonstrates how to load and project GeoJSON data for display. No interactions or styling are applied, keeping the focus on the map layout.
