This example visualizes an ocean-centric interrupted Mollweide projection, using d3.geoInterrupt to combine d3.geoMollweideRaw with custom lobe boundaries that split the globe along landmasses. The map renders world land and country boundaries from TopoJSON, clipped to a spherical outline, with a graticule and a red marker that follows the mouse via projection.invert. It relies on d3.v4, d3-geo-projection, and topojson.v1, drawing everything as SVG paths with d3.geoPath.

AI-generated description

In “Selecting a Map Projection” (Sep. 2012), the National Geographic presented an ocean-centric aspect of an interrupted Mollweide projection.

Interrupted Mollweide

This example depicts the world using an interrupted Mollweide projection, styled after the Goode homolosine to reduce shape distortion across continents. The landmasses are silhouetted in dark gray with white country boundaries, while a graticule overlays the map. The code builds this projection with `d3.geo.interrupt` applied to `d3.geo.mollweide.raw`, defining custom lobes for each hemisphere. It renders geographical data from the world-50m GeoJSON file via `d3.json`, using `d3.geo.path` to draw the sphere, graticule, land, and boundary features into an SVG canvas.

Interrupted Homolosine Oceans

This example renders an ocean-centric interrupted Homolosine projection, highlighting the seas while clipping landmasses and graticules to a spherical boundary. It uses `d3.geoInterrupt` with `d3.geoHomolosineRaw` and custom lobe definitions to split the world into segments. The map displays a mouse-following red marker via `projection.invert`, with land and country boundaries from a TopoJSON `world-50m.json` file. The SVG output is styled with strokes, fills, and a graticule, all drawn using `d3.geoPath`.

Interrupted Sinu-Mollweide

This example demonstrates the Interrupted Sinu-Mollweide map projection, which splits the world map into several lobes that do not extend all the way to the equator, leaving a gap. The map is rendered with SVG using D3.js v3, including the `d3.geo.interrupt` function to define the lobe boundaries and `d3.geo.path` to project geographic features. Land and country boundaries are drawn from a TopoJSON world dataset, with land filled in black and boundaries outlined in white. A graticule and sphere outline complete the visualization, with a clip path restricting all elements to the globe's shape.

Mollweide Hemispheres

This example displays a world map using the Mollweide projection, interrupted into two hemispheres—northern and southern—which are rotated twenty degrees and centered on a 960-by-500 SVG canvas. The map shows landmasses as dark shapes with white country boundaries, overlaid on a graticule, all clipped to a circular sphere. It uses the `d3.geo.interrupt` and `d3.geo.mollweide.raw` projections with `d3.geo.path`, and renders geographic data from a World 50m TopoJSON dataset, drawing both land polygons and a mesh of country boundaries.

Interrupted Boggs Eumorphic

This example shows a world map using the interrupted Boggs eumorphic projection, a composite of the sinusoidal and Mollweide projections. The map displays landmasses, country boundaries, and graticules, with the projection interrupted into separate lobes for the northern and southern hemispheres. The code uses `d3.geo.interrupt` with `d3.geo.boggs.raw` from the geo.projection plugin, along with `d3.geo.path` for rendering SVG paths. It loads world-50m.json via TopoJSON and clips all features to a spherical outline using a clipPath.

Interrupted Homolosine

This example demonstrates D3’s `geoInterruptedHomolosine` projection by rendering a world map with landmasses, country boundaries, and a graticule. It also visualizes the inverse projection by moving a red marker to the geographic coordinates corresponding to the mouse position, using `projection.invert`. The map uses `d3.geoPath` with SVG, TopoJSON for world data, and `d3.geoGraticule`, clipped to a spherical outline. The projection is fitted to the viewport with `fitExtent`.

Interrupted Sinusoidal

This example shows an interrupted sinusoidal projection of the world map, with the globe split into separate lobes in both hemispheres to emphasize land masses. The asymmetrical lobe boundaries, based on the Nordisk Världs Atlas, are visible through the white borders between countries. The visualization uses `d3.geoInterrupt` with `d3.geoSinusoidalRaw` to define the projection, and `d3.geoPath` to render the sphere, graticule, land, and country boundaries. Geographic data comes from the `world-50m.json` TopoJSON file, which is processed with `topojson.feature` and `topojson.mesh`.

Mollweide

This example shows a world map projected using the Mollweide projection, with graticule lines, land masses in dark fill, and country boundaries in white. The map is rendered as SVG using D3 v3 with the `d3.geo.mollweide` projection, `d3.geo.path`, and `d3.geo.graticule`. Land and boundary data come from a TopoJSON file of world countries, processed with `topojson.feature` and `topojson.mesh`. The code defines sphere, stroke, fill, graticule, land, and boundary CSS classes to style the visual layers.
