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.

AI-generated description

The Eckert IV projection is available as d3.geo.eckert4 in the geo.projection D3 plugin.

Eckert III

This example demonstrates the Eckert III map projection, a pseudocylindrical projection that preserves equal area. The SVG canvas displays a graticule and world map, with landmasses rendered in dark gray and country boundaries in white. Using the D3 v3 library, the code employs `d3.geo.eckert3()` for the projection, `d3.geo.path()` to draw geographic paths, and `d3.geo.graticule()` to generate the grid. The world map data is loaded from a remote GeoJSON file via `d3.json()` and transformed using the TopoJSON library.

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.

Eckert II

This example demonstrates the Eckert II projection, a pseudocylindrical equal-area map projection, applied to a world map. A graticule overlays the projection to show latitude and longitude lines, while landmasses appear in dark gray with white country boundaries. The visualization loads world data from a TopoJSON file and renders it using D3 v3’s `d3.geo.eckert2` projection and `d3.geo.path` for SVG paths. Spherical outlines are drawn via a sphere path, and the graticule is generated with `d3.geo.graticule`.

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 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.

Eckert–Greifendorff

This example visualizes the Eckert–Greifendorff projection, a custom variant of the Hammer projection with a coefficient of 4, by displaying world landmasses and country boundaries overlaid on a graticule. The spherical outline is drawn with a white fill and black stroke, while land appears in dark gray. It uses D3 v3, the `d3.geo.hammer` plugin, and TopoJSON to load and render the world-50m dataset via SVG paths. The projection is configured with a scale and translation to center the map.

Van der Grinten IV

This example displays a world map using the Van der Grinten IV projection, filled with dark land masses and white country boundaries against a graticule grid. The map is rendered as SVG using D3 v3, with the projection accessed via `d3.geo.vanDerGrinten4` from the geo.projection plugin. Geographic data comes from a TopoJSON file of world land and country shapes, processed with `topojson.feature` and `topojson.mesh`. A sphere outline and graticule are drawn with `d3.geo.path` and `d3.geo.graticule`.

World Map

This world map visualizes global landmasses and country boundaries using an Eckert III projection. It renders the sphere, graticules, and interior borders as SVG paths, with landmasses filled in purple and graticules in blue. The visualization is built with React, D3 v5’s `geoNaturalEarth1`, `geoPath`, and `geoGraticule`, and TopoJSON’s `feature` and `mesh` to process the world-atlas dataset.
