This example shows a world map in an Albers equal-area conic projection, with landmasses drawn in dark gray, country boundaries in white, and a graticule overlaid on a sphere outline. It uses d3.geo.conicEqualArea with a precision setting for resampled geometries, and d3.geo.path to render the projected features. Graticule lines are generated via d3.geo.graticule, while the land and boundary data come from a TopoJSON file fetched with d3.json, processed through topojson.feature and topojson.mesh. The SVG output uses class-based styling for strokes and fills.

Albers without Resampling

This example demonstrates the Albers equal-area conic projection applied to a world map, comparing land and boundary rendering with and without coordinate resampling. The map displays graticules, country boundaries, and landmasses in black and white, using Geographic Information System data from a TopoJSON file of 110m resolution. The code uses d3.geo.conicEqualArea and d3.geo.path, with the projection’s precision set to zero before drawing the land and country meshes via topojson.feature and topojson.mesh. A graticule layer and a sphere outline are added using d3.geo.graticule, all rendered as SVG elements.

Albers Equal-Area Conic

The visualization demonstrates the Albers equal-area conic projection, a standard map projection commonly used for the United States. It displays the country’s landmass, county boundaries, and state lines over a graticule grid, with a dark land fill contrasted against white administrative borders. The code uses d3.geo.albers with custom rotation, center, parallels, and scale parameters, and renders geographic features via d3.geo.path. TopoJSON data from a remote source is parsed with topojson.feature and topojson.mesh to draw the land and boundary layers, while d3.geo.graticule generates the grid.

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.

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.

Alaska Albers

This example displays Alaska using the EPSG:3338 Alaska Albers equal-area projection, rendered with SVG paths for land and county boundaries over a graticule grid. It filters Alaska state and county geometries from a TopoJSON file of U.S. data, styling land in dark gray and boundaries in white. The code uses `d3.geo.conicEqualArea` with specified rotation, center, and parallels, along with `d3.geo.path`, `d3.geo.graticule`, and `topojson.feature`/`topojson.mesh` to draw the shapes.

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 Siberia

This example displays a map of Russia using the Albers Siberia projection, a customized conic equal-area projection that re-centers and rotates the standard Albers projection to better represent the country’s vast territory. The map renders in SVG, with the geographic data loaded from a local TopoJSON file. The code leverages D3 v3 APIs, including `d3.geo.albers()`, `d3.geo.path()`, and `topojson.feature()` to project and draw the polygon geometries.

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.
