This example displays a map of the United States drawn entirely on a Canvas element. It shows how D3’s `d3.geoPath` can render geographic data into a native Canvas context rather than an SVG, with the map’s geometry provided by the `us-atlas` dataset. The code uses `d3.json` to load the TopoJSON file and `topojson.mesh` to convert it into renderable shapes. The resulting path is stroked onto the canvas via the `context` set on `d3.geoPath`, demonstrating a performant alternative to SVG for large spatial datasets.

AI-generated description

D3’s d3.geoPath can be used with Canvas, not just SVG! This geometry is from us-atlas.

d3.geoPath + Canvas

This example renders the U.S. state boundaries from the `us-atlas` TopoJSON file onto an HTML5 Canvas element. It uses `d3.geoPath` with a Canvas context to draw the map, demonstrating that this projection API works outside of SVG. The code fetches the geographic data from `10m.json`, converts it with `topojson.mesh`, and strokes the resulting paths with a single `beginPath` and `stroke` call. The approach eliminates SVG overhead by relying on Canvas rendering.

d3.geoPath + node-canvas

This example demonstrates how to render geographic data to a Canvas element using d3.geoPath with node-canvas, producing a stroked mesh of United States county boundaries. The rasterize script loads US Atlas TopoJSON data, converts it to GeoJSON with topojson-client, and passes it through d3.geoPath’s context method to draw paths into a 960×600 canvas. It then writes the resulting bitmap to a PNG file, showing server-side vector-to-raster conversion without a browser.

topojson.topology + topojson.mesh

This example demonstrates the Aitoff map projection of the United States, drawn on a Canvas element using D3.js. It renders the geographic boundaries as stroked and filled paths, created via `d3.geoPath` with the `d3.geoAitoff` projection. The code first reads a GeoJSON file containing the US shape, converts it to a topology using the `topojson.topology` function from the `unpkg.com/topojson` package, and then draws it with `topojson.mesh` from `d3js.org/topojson.v2`.

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

This example renders a map of the United States using state boundaries. The map is drawn as black paths with white strokes on an SVG canvas. The code loads GeoJSON state outlines from the `us-atlas` package, converts them into topological features with the `topojson` library, and projects them using `d3.geoAlbers` with `d3.geoPath` for rendering. The visualization demonstrates a basic choropleth-ready framework without additional data encoding.

U.S. States TopoJSON

This example shows a map of the United States rendered as SVG paths, where individual states turn red when hovered. The map uses the TopoJSON `us-atlas` file, loaded via `d3.json`, and the code relies on the `topojson` library to convert the TopoJSON topology into geographic features. The rendering is done with `d3.geoPath` to project the geometry, and state borders are drawn as a separate path using a mesh that highlights each boundary. No interaction beyond the hover effect is implemented.

U.S. TopoJSON

This example displays a layered map of the United States using county, state, and national boundaries. The map is rendered as SVG, with counties stroked in thin gray, states in thin black, and the nation in a thicker black outline. It loads TopoJSON data from the us-atlas package and uses the topojson-client library to compute and draw the geographic meshes and features. The visualization is built with d3.v4, using d3.json for data fetching and d3.geoPath for path generation.

Let's make the US Map with D3.js!

This example displays a choropleth-style map of the United States with state boundaries rendered as SVG paths. It uses D3.js v5 to load US Atlas TopoJSON data, converts it to GeoJSON with the topojson library’s `feature` function, and projects it using `d3.geoAlbersUsa`. The `geoPath` generator draws each state as a separate path with a light green fill and subtle black strokes. A light blue sphere background is added first to contrast with the landmasses. The visualization intentionally omits labels or interactive features, focusing strictly on the geographic outlines.

Country Map

This example visualizes a map of the United States, rendering individual state boundaries as green paths with dark strokes on a light blue SVG canvas. It uses the D3 v4 library with `d3.geoPath` and the `d3.geoAlbersUsa` projection to draw the map, while `topojson-client` converts TopoJSON data from the us-atlas dataset into GeoJSON features. The SVG is styled with a custom background color and positioned within a React-free HTML page, with margins and transform attributes controlling the layout.
