Eckert I

This example displays a world map using the Eckert I projection, with landmasses filled in dark gray and country boundaries outlined in white against a graticule grid. The spherical outline is drawn with a thick black stroke and white fill, emphasizing the projection’s oval shape. The visualization uses D3 v3, the `d3.geo.eckert1` projection from the geo.projection plugin, and `d3.geo.path` to render geographic features. World data comes from a TopoJSON file (`world-50m.json`), processed with `topojson.feature` and `topojson.mesh` to separate land and country boundaries.

Eckert VI

This example demonstrates the Eckert VI map projection, a pseudocylindrical equal-area projection that displays the entire globe within an ellipse. The map shows world land masses as dark regions with white country boundaries overlaid on a graticule, all rendered as SVG. The code uses the D3 v3 library with the `d3.geo.eckert6` projection plugin, `d3.geo.path` for projecting geographic features, and `d3.geo.graticule` for the coordinate grid. World data comes from a 50m resolution GeoJSON file loaded via `d3.json`, and TopoJSON is used to extract land and boundary shapes.

Maurer No. 73

This example visualizes the world map using the Maurer No. 73 projection, a pseudonic equal-area projection that warps continents into a curved, flower-like shape. The map displays landmasses in dark gray with white country boundaries, overlaid with a graticule and enclosed by a circular sphere outline. It uses D3 v3 with the `d3.geo.hill` projection from the geo.projection plugin, rendered as SVG via `d3.geo.path`. Geographic data comes from a TopoJSON world dataset loaded with `topojson.feature` and `topojson.mesh`.

Eckert V

This example displays a world map on the Eckert V projection, rendered in SVG for a 960-by-500 viewport. It uses the `d3.geo.eckert5` projection from the geo.projection plugin and `d3.geo.path` to draw graticules, landmasses from a TopoJSON world-50m file, and country boundaries derived via `topojson.mesh`. The map is styled with contrasting strokes and fills against a light 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.

Equirectangular (Plate Carrée)

This example demonstrates the equirectangular (Plate Carrée) projection, a simple geographic mapping where latitude and longitude are plotted linearly on a flat grid. The visualization displays world landmasses in dark gray and country boundaries in white, overlaid with a graticule grid at half opacity. The code uses d3.geoEquirectangular to define the projection, d3.geoPath for rendering, and topojson to parse world-50m.json data. The map is drawn as SVG paths with styling for land, boundaries, and graticule layers.

Boggs Eumorphic

This example displays a world map using the Boggs eumorphic projection, an average of the sinusoidal and Mollweide projections. The map is rendered as SVG with landmasses in black and country boundaries in white, overlaid on a graticule. The code uses `d3.geo.boggs`, `d3.geo.path`, and `d3.geo.graticule` from the D3 v3 geo projection plugin, with geographic data loaded from a world-50m GeoJSON file.

Eckert IV

This example demonstrates the Eckert IV map projection, a pseudocylindrical equal-area projection that renders the entire world on a 960 by 500 pixel SVG canvas. The visualization displays the projected globe with graticule lines, landmasses in dark gray, and country boundaries in white. Using D3.js v3, the code employs `d3.geo.eckert4()` alongside the `d3.geo.path`, `d3.geo.graticule`, and the `d3.geo.projection` plugin to construct paths. World map data comes from a GeoJSON file containing 50-meter resolution land and country features, processed through TopoJSON.
