Cylindrical Stereographic

Stereographic

A world map is displayed using the stereographic projection, showing landmasses in dark gray and country boundaries in white over a graticule grid. The projection rotates the globe by -20 degrees longitude and clips the view to a square. Built with D3 v3, the example uses `d3.geo.stereographic`, `d3.geo.path`, and `d3.geo.graticule`, rendering SVG paths from TopoJSON world data. The graticule is drawn beneath the land and boundary layers.

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.

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.

Gnomonic

This example shows the world map projected using the gnomonic projection, where great circles appear as straight lines and distortion increases toward the edges. The map is clipped at a 90-degree angle, displaying landmasses in dark gray with white country boundaries over a graticule grid. The visualization uses D3 v3’s `d3.geo.gnomonic` projection and `d3.geo.path` to render SVG paths from TopoJSON world data, with the graticule drawn via `d3.geo.graticule`. The code sets projection scale, translation, and precision before loading the `world-50m.json` file.

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.

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.

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.
