This example displays a world map using the quartic authalic projection, a variant of the Hammer projection with an infinite coefficient, resulting in a distinctive flattened and stretched appearance. The map shows landmasses in dark gray with white country boundaries, overlaid on a graticule grid, all enclosed within a circular sphere outline. Built with D3 v3, it uses `d3.geo.hammer()` with a coefficient of `Infinity` to define the projection, `d3.geo.path()` for rendering, and TopoJSON to load world-50m geographic data. The SVG output includes styled paths for the sphere, graticule, land, and boundaries.

Flat-Polar Quartic

This example displays a world map projected using the flat-polar quartic projection, which flattens the poles into curved, diamond-like shapes. The map shows landmasses in dark gray with country boundaries in white, overlaid on a graticule grid and enclosed by a circular sphere outline. It uses D3 v3 with the `d3.geo.mtFlatPolarQuartic` projection, `d3.geo.path` for rendering SVG paths, and TopoJSON to load world-50m geographic data. A graticule layer is generated via `d3.geo.graticule`, and the sphere outline is reused as both stroke and fill.

Hammer Retroazimuthal

This example displays a world map using a Hammer retroazimuthal projection, centered on parallel 52°N, with vector land and boundary outlines rendered as SVG paths clipped to the projected sphere. The code uses d3.geo.path with a custom projection and d3.geo.graticule to draw the graticule, while topojson.v1 loads and processes the world-50m GeoJSON data for land and country boundaries. A white stroke highlights the map boundary, and the projection’s clip angle ensures no artifacts appear beyond the map’s edge.

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.

Hammer

The example shows a world map using the Hammer projection, with landmasses rendered in dark gray and country boundaries outlined in white against a graticule. It demonstrates how the projection’s coefficient B can be customized, though the code displays the default B=2. Using D3 v3, it applies `d3.geo.hammer` from the geo.projection plugin, `d3.geo.path` for geographic rendering, and `d3.geo.graticule` for the grid. TopoJSON data from a remote world-50m file is converted with `topojson.feature` and `topojson.mesh` to draw land and boundaries into an SVG.

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.

Peirce Quincuncial

This example shows the Peirce quincuncial projection, a conformal map that projects the globe onto a square using a complex algorithm. The visualization displays world landmasses in dark gray with white country boundaries, overlaid on a graticule of meridians and parallels, all within a 960-pixel SVG. The code uses `d3.geoPierceQuincuncial()` from the d3-geo-projection library to define the projection, and `d3.geoPath()` to render the projected geometry. It loads world data from a TopoJSON file, specifically via `topojson.feature` for land and `topojson.mesh` for country boundaries. The sphere is outlined in black, and the rendering is handled with SVG paths.

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.

Nell–Hammer

This example shows the Nell–Hammer map projection, a pseudocylindrical equal-area projection that renders the entire globe as an ellipse. It displays world landmasses in dark gray, country boundaries in white, and a graticule of meridians and parallels in light gray. The code uses the `d3.geo.nellHammer` projection from the `d3.geo.projection` plugin, with `d3.geo.path` to draw the projected geometry. Land and boundary data come from a TopoJSON source (`world-50m.json`), processed via the `topojson` library. Rendering is done with SVG, and the sphere outline is defined once as a reusable `<defs>` element.
