Wagner VI

Wagner VII

This example displays a world map using the Wagner VII projection, a compromise projection that balances area and shape distortion. A graticule overlays the globe, with landmasses filled in dark gray and country boundaries marked by thin white lines. The visualization loads geographic data from a TopoJSON file containing world land and country boundaries. Rendered as SVG, the code uses D3 v3’s `d3.geo.wagner7` projection, `d3.geo.path`, and `d3.geo.graticule`, alongside TopoJSON’s feature and mesh methods to extract and draw the spatial data.

Wagner IV

The Wagner IV projection, also known as Putniṇš P2´, is displayed as an interactive SVG world map with a graticule and country boundaries. The visualization uses `d3.geo.wagner4` from the geo.projection plugin, `d3.geo.path` for rendering, and TopoJSON data from a world-50m file to draw landmasses and boundaries. A spherical outline is defined and reused via SVG `<use>` elements for stroke and fill styling.

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 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.

Werner

This example displays a world map using the Werner projection, a specific map projection that shapes the globe into a heart-like form. The visualization renders the map with land areas in dark gray, country boundaries in white, and a graticule overlay. The code builds the map with the D3.js library and its `d3.geo.bonne` projection, using `d3.geo.path` and `d3.geo.graticule` to draw the map features. World land and country data is loaded from a TopoJSON file fetched with `d3.json`.

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`.

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 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.
