Aitoff

This example displays a world map using the Aitoff projection, a compromise projection that represents the entire globe in an ellipse. The map shows landmasses in dark gray and country boundaries as white lines over a graticule of latitude and longitude lines. Built with D3 v3 and the `d3.geo.aitoff` projection from the geo.projection plugin, it uses `d3.geo.path` to render the sphere, graticule, and land features. The world data is loaded as TopoJSON from a remote gist and processed with `topojson.feature` and `topojson.mesh`.

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.

August Projection

This example displays a world map using the August projection, a pseudocylindrical equal-area projection that curves parallels and meridians into distinctive intertwined shapes. The map renders land masses in dark gray with white country boundaries overlaid on a graticule, all enclosed within a spherical outline. Using D3 v3, the code employs `d3.geo.august` for the projection, `d3.geo.path` to draw geographic features, and `d3.geo.graticule` for the grid. TopoJSON data provides the world land and country boundaries, loaded from an external JSON file.

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.

Equidistant Conic Projection

This example shows a world map drawn with the equidistant conic projection, including a graticule, landmasses, and country boundaries. The map is rendered as SVG using D3’s `d3.geo.conicEquidistant` projection and `d3.geo.path` to generate the paths. A sphere outline and graticule are drawn first, then geographic data from a TopoJSON file (`world-50m.json`) is loaded with `topojson.feature` and `topojson.mesh` to display land and political borders.

Tobler–Mercator

This example demonstrates the Tobler–Mercator projection, a modified Mercator projection that preserves area. The world map is rendered with graticule lines, country boundaries, and a white sphere outline. Built with D3 v4, it combines `d3.geoProjection` with a custom projection function and `d3.geoPath` for geographic rendering. The map uses TopoJSON data from the world-atlas package, with land and country boundary geometries loaded via `d3.json` and processed using `topojson.feature` and `topojson.mesh`. The visualization is fully SVG-based.

Let's make a map with D3.js!

This example shows a world map rendered as SVG, with countries filled in light green against a blue sphere, using a natural Earth projection to display the globe. The code loads GeoJSON country boundaries from the world-atlas TopoJSON dataset and converts them using the `feature` function from topojson. D3’s `geoPath` and `geoNaturalEarth1` projection generate the geographic paths, while a separate path outlines the spherical backdrop. The visualization is minimal, focusing on a clean, interactive-free display of global landmasses.
