Satellite Projection

This example shows a satellite projection of the United States, with a graticule overlay and land boundaries rendered as SVG paths. The projection is created with `d3.geo.satellite()`, configured with a distance, scale, rotation, center, and tilt to simulate a view from space. The graticule is generated using `d3.geo.graticule()` and the map data is loaded from an external JSON file via `d3.json`. The code uses `d3.geo.path()` with the projection to draw both the graticule and the land polygons, which are converted from TopoJSON using `topojson.feature()`.

Multiple Rotations

An animated canvas displays a rotating globe. The graticule and sphere are drawn using D3’s geometry pipeline, which applies two sequential rotations—a fixed tilt and a time-based spin—before orthographic projection and clipping. The code uses `d3.geo.pipeline` with `d3.geo.rotate`, `d3.geo.clipCircle`, and `d3.geo.project`, rendering via a `contextSink`. The graticule is generated by `d3.geo.graticule`.

This Is Not a Globe

This visualization presents a stylized, rotating globe built from world land boundaries using an equirectangular projection. The land data is drawn onto a circular canvas clip, with two offset copies of the map scrolling horizontally to create the illusion of continuous rotation. The code uses the D3.js `d3.geo.equirectangular` projection, `d3.geo.path`, and Canvas `context` APIs, driven by a timer to update the animation. The world-110m GeoJSON dataset provides the geographic features, and the animation simulates a sphere while the actual projection remains flat.

This Is a Globe

A rotating orthographic globe displays Earth’s landmasses as a flat silhouette on a circular canvas. The map is rendered using D3 v3’s `d3.geo.orthographic` projection and `d3.geo.path`, with TopoJSON land data from the world-110m file. A `d3.timer` advances the rotation each frame, clearing and redrawing the canvas context, while a stroked arc outlines the sphere’s edge.

Spinny Globe

A sphere rotates continuously, displaying only the visible front hemisphere through a navigable orthographic projection. The example uses D3’s `d3.geo.orthographic` projection with great-circle clipping and renders land geometries onto a Canvas via `d3.geo.path`. The rotation is driven by a `d3.timer` that updates the projection’s rotation over time. Land data comes from Natural Earth’s world-110m dataset, loaded as TopoJSON.

Pencil Sketch

A rotating globe appears hand-drawn, with landmasses rendered as multiple overlapping, jittered outlines in a sketchy style. The visualization uses D3’s geometry pipeline to resample, jitter, and smooth points along great arcs for a hand-drawn effect. It renders to a canvas element, animating the globe’s rotation over time. The code loads world map data from a JSON file and draws it using an orthographic projection.

Spinning Globe

A spinning globe rendered with an orthographic projection, showing country boundaries from the visionscarto World Atlas TopoJSON dataset. The view rotates continuously around its vertical axis using `requestAnimationFrame` to incrementally adjust `projection.rotate`. Built with `d3.geoOrthographic`, `d3.geoPath`, and `d3.geoGraticule`, the animation highlights the graticule lines, country outlines, and a bold sphere outline as the Earth turns.
