Interrupted Homolosine

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 Homolosine Condensed (Work In Progress)

This is a work-in-progress D3 v4 visualization exploring a "condensed" variant of the interrupted Homolosine projection, as seen in Herbert Bayer's World Geographical Atlas. It displays a world map with landmasses and country boundaries, split into two distinct projection configurations side-by-side. The code uses `d3.geoInterruptedHomolosine` with custom `clipPolygon` and `lobes` definitions, rendering via `d3.geoPath` over SVG. A graticule layer and a red marker that tracks the mouse position via `projection.invert` are also included, using TopoJSON world data.

Interrupted Goode Homolosine

This example demonstrates the Interrupted Goode Homolosine projection, a composite map projection that divides the world into lobes to minimize distortion. The visualization renders land masses in dark gray, country boundaries in white, and a graticule over a sphere outline, all clipped to the projection’s shape. It uses the `d3.geo.interrupt` and `d3.geo.homolosine` functions from the `d3.geo.projection` plugin, along with `d3.geo.graticule`, `d3.geo.path`, and TopoJSON data from the `world-50m.json` source.

Interrupted Mollweide Oceans

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.

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.

InterruptedSinuMollweide inverse projection

This example demonstrates the inverse of the InterruptedSinuMollweide projection, visually validating that the projection and its inverse accurately map points on a sphere. A grid of points is rendered in green when the forward and inverse projections agree, red when they disagree, and blue when inversion fails. The code uses d3-geo-projection's `d3.geoInterruptedSinuMollweide` and `d3.geoPath` to draw the graticule and world map from TopoJSON data. The inverse computation relies on `d3.geoSolve`, and the visualization is rendered as an SVG with interactive mouse tracking.

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.

Interrupted Sinusoidal II

This example displays a world map using an interrupted sinusoidal projection, splitting the globe’s landmasses into separate lobes for the northern and southern hemispheres. The map uses a white graticule and country boundaries over dark land areas, all clipped to a sphere outline. The visualization relies on d3-geo-projection’s `geoInterrupt` and `geoSinusoidalRaw` functions, with paths drawn using `d3.geoPath`. Geographic data comes from a world-50m GeoJSON file, processed via the topojson library, and rendered as SVG elements.
