This example visualizes world landmasses and country boundaries using a Lambert azimuthal equal-area projection, centered on the globe to produce a circular map. The graticule and sphere outline frame the map, while land is filled dark against a light background. Built with D3 v4, it uses `d3.geoAzimuthalEqualArea` for projection, `d3.geoPath` for rendering shapes, and `d3.geoGraticule` for the grid, pulling geographic data from a world-50m JSON dataset via `topojson`. The SVG output is styled with CSS classes for land, boundaries, and graticule.

AI-generated description

The Lambert azimuthal equal-area projection is available as d3.geo.azimuthalEqualArea. See also the polar aspect of this projection. This projection is also a special case B = 1 of the Hammer projection.

Polar Azimuthal Equal-area

This example visualizes the Earth using the polar azimuthal equal-area projection, with landmasses in black and country boundaries in white against a graticule. The map is centered on the North Pole and rendered as an SVG, with a sphere outline and fill. The code uses `d3.geo.azimuthalEqualArea()` for the projection and `d3.geo.path()` to draw features from a TopoJSON world dataset loaded via `d3.json`.

Lambert Conformal Conic

The example shows a world map rendered with the Lambert conformal conic projection, using a graticule and sphere outline to clarify the projection’s shape. It displays landmasses in dark gray and country borders as thin white lines over a light background. The visualization uses d3.geoConicConformal to define the projection, d3.geoPath to generate SVG paths, and topojson.feature and topojson.mesh to extract land and border geometries from the world-50m dataset. The graticule is drawn with d3.geoGraticule10, and all elements are rendered as SVG paths.

Azimuthal Equidistant

This example demonstrates the azimuthal equidistant projection, a map projection that preserves accurate distances from a central point. The map is centered on San Francisco, with the world rendered using outlines and filled landmasses. The visualization uses D3’s `d3.geoAzimuthalEquidistant` projection and `d3.geoPath` to draw the sphere, graticule, and geographic features. Land and boundary data come from a world-atlas TopoJSON file, processed using the `topojson-client` library. The SVG output includes a graticule, a stroked sphere outline, and a white-filled sphere background.

Cylindrical Equal-Area

This example shows a world map rendered using the cylindrical equal-area projection, with dark landmasses and light country boundaries overlaid on a graticule. The projection’s shape is modified by selecting different standard parallels, such as Gall–Peters or Hobo–Dyer, highlighting how the choice affects the map’s proportions. The visualization uses `d3.geoCylindricalEqualArea` and `d3.geoPath` from the `d3-geo-projection` library to draw the paths, while geodata is loaded as TopoJSON from a GitHub-hosted file. The SVG output is styled with CSS classes for the graticule, land, and boundaries.

Larrivée

This example displays a world map using the Larrivée projection, a pseudocylindrical equal-area projection that resembles a flattened globe with curved meridians. Landmasses appear as dark shapes with white country boundaries, set against a graticule and a spherical outline. The map is rendered with SVG via D3’s `d3.geo.path` and the `d3.geo.larrivee` projection from the geo.projection plugin, while TopoJSON data (`world-50m.json`) supplies the land and country meshes. The visualization includes a graticule layer and a white-filled sphere background.

Transverse Mercator

This example demonstrates the transverse Mercator map projection, displaying world landmasses and country boundaries within a graticule grid. The map is rendered as SVG using the D3.js library, specifically employing the `d3.geoTransverseMercator` projection and `d3.geoPath` for drawing geometries. World data comes from the `world-atlas` package, processed with `topojson-client` to extract land and boundary features. The visualization includes a spherical outline, a graticule, and styled land and boundary paths, all centered within a 960x960 canvas.

Spherical Mercator

The example shows the spherical Mercator projection applied to a world map, displayed within a circular outline that represents the globe. The map renders landmasses in dark gray with white country boundaries, overlaying a graticule grid of meridians and parallels. Built with d3.geoMercator and d3.geoPath, it draws the sphere outline, graticule, and world geography via SVG paths. Geographic data comes from the world-atlas TopoJSON dataset, processed with topojson-client to extract land and country meshes.

Loximuthal

This example displays a world map using the Loximuthal projection, a pseudocylindrical equal-area projection. The map shows landmasses in black with white country boundaries overlaid on a graticule, all enclosed within a circular sphere outline. The visualization uses d3.geo.loximuthal from the extended geographic projections plugin, along with d3.geo.path and d3.geo.graticule to render the vector data. TopoJSON provides the world-50m geographic data, which is converted to GeoJSON features and meshes for the land and boundary layers.
