This example presents a modified Albers USA map projection that includes Puerto Rico, rendered as an SVG using D3.js v3 and TopoJSON. The code defines a custom `albersUsaPr()` function, which composes four separate conic equal-area projections for the lower 48 states, Alaska, Hawaii, and Puerto Rico, each with its own translation and clipping. The map displays graticules and a sphere outline via `d3.geo.graticule()` and `d3.geo.path()`, and it loads US state boundaries from an external JSON file. Interactive mouse movement logs the projected coordinates using `projection.invert()`.

AlbersUSA inverse proj parameters

This block demonstrates the inverse projection parameters of a modified AlbersUSA projection that includes Puerto Rico, answering a D3.js issue. It renders a U.S. map with red and green guide lines and rectangles marking the boundaries of each sub-projection’s clip extents within the composite projection’s coordinate space. The code uses `d3.geoAlbers`, `d3.geoConicEqualArea`, `d3.geoPath`, and `d3.geoGraticule` with SVG output. It overlays graticules, a sphere outline, and a red center point, while the map mesh comes from TopoJSON data.

Albers USA

This example illustrates the Albers USA composite projection by dividing the map into four colored regions, each labeled with the conditional rule that determines which part of the United States it represents. It overlays a world map and graticule to show the geographic context. The visualization uses D3 v3 with `d3.geo.mercator`, `d3.geo.mercator`, `d3.geo.path`, and `d3.geo.graticule` to project and render SVG paths, while the division rectangles and lines are drawn manually to mark the Alaska, Hawaii, Puerto Rico, and lower-48 regions. World land data comes from a remote TopoJSON file.

Untitled

This example displays a map of the United States, including Alaska, Hawaii, and Puerto Rico, using a custom composite projection defined in `albers-usa-pr.js`. The code builds on `d3.geoAlbers` and `d3.geoConicEqualArea` to create `d3.geoAlbersUsaPr`, which is then used with `d3.geoPath` to render state boundaries from TopoJSON data in `states.js`. SVG paths are generated for each state, filled gray with white strokes.

Albers Projection

This example displays a map of the United States using the Albers projection, with each state drawn as a filled gray polygon with white outlines. The visualization loads GeoJSON data from a remote `us.json` file via `d3.json`, which is then converted into SVG paths using `topojson.feature` and `d3.geo.path()`. The map is rendered as a single SVG path element within a 960×500 canvas, demonstrating a basic static choropleth without additional interactivity or styling layers.

Albers Projection

This example displays a map of the United States using the Albers projection, a conic equal-area projection commonly used for national-scale choropleths. It renders the geographic boundaries as gray SVG paths with white strokes, loaded from a local `states.json` GeoJSON file. The code uses the D3 v3 library, specifically the `d3.geo.albers()` projection and `d3.geo.path()` to project and draw the feature collection.

US Map Projection

This example displays a map of the United States using an Albers equal-area conic projection, with the landmass filled in light gray and state boundaries in white. It uses D3.js (d3.v7) with the `d3.geoAlbersUsa()` projection and the `d3.geoPath()` function to render the geographic shapes as SVG paths. The map is drawn within a fixed 960×600 viewport, and the underlying geographic data is handled by the TopoJSON library.

GeoAlbers with Territories

This example displays US state boundaries using the geo-albers-usa-territories projection, which extends the standard Albers projection to include Alaska, Hawaii, and US territories. The map renders state outlines and interior borders as SVG paths, with land filled in teal and boundaries in a lighter contrasting stroke. The code loads US Atlas TopoJSON data and converts it to GeoJSON using `topojson.feature` and `topojson.mesh`. It builds the visualization with React components, `d3.geoPath` for projection and path generation, and `d3.geoGraticule` for the background graticules.

This example displays a map of the United States using an Albers USA projection, rendering state boundaries as SVG paths. It loads geographic data from a local `us-states.json` file containing a FeatureCollection of state polygons. The code uses d3.json to fetch the data and d3.geo.path with a d3.geo.albersUsa projection to convert GeoJSON coordinates into screen paths. The visualization presents a simple, static outline map without additional data encoding or interaction.
