The Patterson cylindrical projection renders world landmasses with country boundaries over a graticule, balancing polar exaggeration between Miller and Plate Carrée projections. Built with d3.v4 and d3-geo-projection, it applies `d3.geoPatterson()` to a `d3.geoPath` generator, scaling and translating to a 960×547 SVG canvas. Land and mesh data come from TopoJSON’s world-50m.v1, styled via CSS classes for land, boundaries, and graticule. The projection’s precision is set to 0.1 for smooth geometry.

AI-generated description

The Patterson cylindrical projection “falls between the popular Miller 1, which excessively exaggerates the size of polar areas, and the Plate Carrée, which compressess the north-south dimension of mid latitudes.”

Flat-Polar Parabolic

A flat-polar parabolic projection maps the world onto an oval-shaped canvas, with landmasses filled in dark gray and country boundaries marked by thin white lines. The visualization also includes a graticule grid and an outer sphere outline, rendered as SVG paths using d3.geo.path and the d3.geo.mtFlatPolarParabolic projection. Geographic data comes from a TopoJSON world file, processed via topojson.feature and topojson.mesh. The projection scale and translation are set explicitly, with precision configured for smooth rendering.

Cylindrical Equal-Area

This example shows a world map rendered using the cylindrical equal-area projection, with dark landmasses and light country boundaries overlaid on a graticule. The projection’s shape is modified by selecting different standard parallels, such as Gall–Peters or Hobo–Dyer, highlighting how the choice affects the map’s proportions. The visualization uses `d3.geoCylindricalEqualArea` and `d3.geoPath` from the `d3-geo-projection` library to draw the paths, while geodata is loaded as TopoJSON from a GitHub-hosted file. The SVG output is styled with CSS classes for the graticule, land, and boundaries.

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.

Cylindrical Stereographic

A world map is rendered using the cylindrical stereographic projection, showcasing global landmasses and country boundaries over a graticule grid. The visualization uses the `d3.geoCylindricalStereographic` projection from the d3-geo-projection plugin, with `d3.geoPath` drawing the geographic features. Land areas are filled dark, while country borders appear as white lines, and the sphere outline is traced in black. The map is built from TopoJSON world data loaded via `d3.json`, with geographic features extracted using the `topojson.feature` and `topojson.mesh` APIs.

Rectangular Polyconic

This example demonstrates the rectangular polyconic map projection, a pseudoconical projection that renders the world with curved meridians and straight parallels. The map shows landmasses in dark gray with country boundaries in white, overlaid on a graticule grid and enclosed by a spherical outline. Built with D3.js v3, it uses `d3.geo.rectangularPolyconic` from the extended projections plugin, `d3.geo.path` for geographic rendering, and `d3.geo.graticule` to generate the grid. World geometry comes from a TopoJSON file loaded via `topojson.feature` and `topojson.mesh`.

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.

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.

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.
