A coloring-book-style map of the United States lets visitors paint individual states by clicking or dragging, with a palette of nine colors selectable via mouse or number keys. The visualization uses d3.geo.albersUsa and d3.geo.path to render state boundaries from TopoJSON, while d3.behavior.drag manages interactive painting. Merged regions are drawn as SVG paths, and the current color assignments are encoded in the URL hash for sharing.

AI-generated description

Click and drag to paint! Click on the colors or use the number keys to change colors. Copy-and-paste the address bar to share this map with others. There’s a counties version, too.

Paint by Numbers II

This interactive map of U.S. counties lets users paint each county with one of nine colors, with selections shared via a URL hash. Dragging across the map assigns colors, while clicking the legend or pressing number keys switches the active color. Built with D3 v3 and TopoJSON, the visualization uses `d3.geo.albersUsa` for projection, `d3.behavior.drag` for painting, and merges colored counties into SVG paths via `d3.geo.path`. County boundaries are rendered as a mesh, with a background stroke and interactive foreground paths.

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.

Let's make a map with D3.js!

This example demonstrates how to create a choropleth-style map of the United States using D3.js, highlighting a subset of states with a distinct CSS class. It loads TopoJSON data from `https://d3js.org/us-10m.v1.json` and uses `d3.geoAlbersUsa` for projection and `d3.geoPath` to render state boundaries as SVG paths. The code filters state features against a predefined set of FIPS IDs, though the visual highlighting of selected states is commented out.

Let's make a map with D3.js!

This visualization displays U.S. states as a choropleth map, highlighting a subset of selected state IDs in orange while rendering all others in gray. It uses D3 v5’s `geoAlbersUsa` projection and `geoPath` to draw SVG paths from TopoJSON data loaded from `us-10m.v1.json`. The code filters state features against a predefined set and applies the `.selected` CSS class, though the commented-out section means the highlighting is not rendered in the final output.

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

This interactive US map uses d3.geoAlbersUsa and d3.geoPath to render state boundaries from TopoJSON data, with each state displaying its name via SVG title elements. The visualization supports zooming and panning through d3.zoom, applying transforms to the SVG group containing the state paths. States are colored light green and highlight on hover, while the surrounding ocean appears as a light blue sphere backdrop. The map loads geographic data from a CDN-hosted US atlas file and renders everything client-side using D3 v5.

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.

Let's make a map with D3.js!

This example shows a simple interactive map of the United States, with each state rendered as a light green shape that turns red on hover. It uses D3 v5’s `geoAlbersUsa` projection and `geoPath` to draw the geography, while TopoJSON’s `feature` extracts state boundaries from the us-atlas counties-10m dataset. The SVG paths are selected and appended via `selectAll` and `data`, with styling handled in CSS. The map is static apart from the hover effect, with no zoom or pan interactions.

US Map

This example displays a map of the 50 US states, with each state filled in red and white borders separating them. The visualization uses the `geoAlbersUsaTerritories` projection and the `d3.geoPath` API to render geographic shapes as SVG paths. The map is generated from TopoJSON data loaded from a remote US atlas source, and it enhances interactivity by changing each state’s color to green when the pointer hovers over it.
