Ginzburg VI

This example displays a world map using the Ginzburg VI polyconic projection, filling landmasses in dark gray against a white globe and overlaying graticule lines and country boundaries. It uses d3.geo.ginzburg6 from the d3.geo.projection plugin, with d3.geo.path for rendering, TopoJSON for world land and country data sourced from a gist, and SVG elements for the sphere, graticule, and hierarchical map layers.

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.

Ginzburg VIII

This example displays a world map using the Ginzburg VIII projection, a pseudocylindrical map projection that curves meridians to create a distinctive, globe-like appearance. The map shows landmasses in dark gray with white country boundaries, overlaid on a graticule grid and enclosed by a circular sphere outline. Built with D3 v3, it uses `d3.geo.ginzburg8`, `d3.geo.path`, and `d3.geo.graticule` to render the projection, graticule, and sphere. Geographic data comes from a TopoJSON file of world land and country boundaries, loaded via `topojson.feature` and `topojson.mesh`.

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.

Craster Parabolic

This example displays a world map projected using the Craster parabolic projection, with graticule lines, country boundaries, and landmasses rendered in SVG. The visualization uses d3.geo.craster from the d3.geo.projection.v0 library, along with d3.geo.path for geographic path generation and topojson.v1 to parse world-50m.json data. A sphere outline and fill are drawn first, followed by graticule and geographic features from the TopoJSON file, with styling applied via CSS classes.

Littrow

The example displays a world map using the Littrow projection, with landmasses in dark gray and country boundaries in white, clipped to a spherical outline. It also overlays a graticule to show latitude and longitude lines. The visualization uses D3 v3 with the `d3.geo.littrow` projection plugin, `d3.geo.path`, and `d3.geo.graticule` to render geographic data from a TopoJSON file containing world land and country boundaries, all drawn as SVG elements.

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.

Ginzburg IV

This example shows a world map using the Ginzburg IV map projection, with landmasses and country boundaries drawn over a graticule and a spherical outline. The visualization uses d3.geo.ginzburg4 and d3.geo.path with SVG rendering, layering a white-filled sphere for reference. It loads world-50m.json TopoJSON data via d3.json, applying topojson.feature for land and topojson.mesh for boundaries. The map uses a black land fill, white boundaries, and gray graticule lines, styled through CSS classes.
