A rotating Winkel Tripel projection continuously spins the world map around its longitude axis. The example shows both landmasses and graticule lines drawn on a canvas, with the rotation driven by a timer that updates the projection’s rotation each frame. It uses D3 v3 with the `d3.geo.winkel3` projection, `d3.geo.path`, and Canvas 2D context, while loading world-110m TopoJSON data. The graticule and its outline are stroked separately to distinguish the grid from the map frame.

Rotating Transverse Mercator

A rotating transverse Mercator projection continuously spins a world map around its central meridian, showing how the projection distorts shapes and areas away from the axis of rotation. The animation uses a dark canvas with white country borders and a semi-transparent graticule, all rendered via `d3.geoPath` and Canvas 2D drawing. Land polygons and country boundaries come from TopoJSON data in the world-atlas package, while a `d3.timer` updates the projection’s rotation each frame. The code specifies `d3.geoTransverseMercator`, `d3.geoGraticule10`, and `topojson.feature` and `topojson.mesh` for data processing.

Winkel Tripel

A world map in the Winkel Tripel projection shows land masses in black with white boundaries, enclosed by a graticule and a spherical outline. The map displays all continents without extreme distortion, using a custom geographic projection. Built with the D3 v3 library, the example loads world-50m.json data and renders SVG paths via d3.geo.path with the d3.geo.winkel3 projection, applying graticule and boundary meshes through topojson.

Rotating Equirectangular

This example displays the world map using an equirectangular projection that continuously rotates horizontally. The visualization is rendered on an HTML5 Canvas element using the D3.js v3 and TopoJSON libraries, with a timer-driven animation. The projection’s rotation angle updates over time based on elapsed milliseconds, clearing and redrawing the filled land polygons each frame. World geometry comes from a remote GeoJSON file of 110-meter resolution, processed with `topojson.feature` and drawn via `d3.geo.path` with Canvas context.

Winkel Tripel Graticule

This example displays a global graticule—a mesh of latitude and longitude lines—projected using the Winkel Tripel projection, with a thicker outline emphasizing the map’s outer boundary. The visualization uses D3 v3’s `d3.geo.winkel3()` projection, `d3.geo.path()` to render the projected geometry, and `d3.geo.graticule()` to generate the grid. The graticule lines and outline are drawn as SVG paths, with the projection scaled and centered to fit a 960×500 canvas.

Rotating Transverse

Two animated map projections rotate in sync on a single canvas: a transverse equirectangular (Cassini) projection on the left and a transverse Mercator on the right. Each frame, `d3.geo.equirectangular` and `d3.geo.mercator` recompute their rotation via `d3.timer`, while `d3.geo.path` renders land from TopoJSON world-110m data and a graticule. The canvas context is manually rotated by 90 degrees to align the transverse orientation.

Rotating Orthographic

A rotating orthographic projection of the world, rendered via canvas animation, shows the globe slowly spinning as landmasses and country borders move across the sphere. The code uses `d3.geo.orthographic` with a clip angle to define the projection, `d3.geo.path` to draw land, borders, and graticule, and `d3.json` to load world-110m GeoJSON data. A timer updates the rotation angle over time, clearing and redrawing the canvas each frame.

Zoom and Rotating (Reprojecting)

This example shows a continuously rotating world map rendered on a Canvas element, with countries and a graticule drawn in grayscale against a dark sphere. Using D3 v4’s `d3.geoMercator` projection, `d3.geoPath`, and `d3.geoGraticule`, the code redefines the projected sphere each frame via a `d3.timer` that increments the rotation speed. Land polygons are loaded from a local `land.geojson` file, and the animation highlights how reprojection affects visible geography as the globe spins.

Rotating Orthographic

An orthographic projection of the world rotates continuously, showing a dark outline of the continents against a circular boundary. The rotation is driven by a timer that recalculates the projection’s center based on elapsed time and a fixed velocity. The example uses `d3.geo.orthographic()`, `d3.geo.path()`, and `topojson.feature()` to render the land from a `world-110m.json` dataset as SVG. The code also applies a 90-degree clip angle and updates the path’s `d` attribute on each tick, with styling from a CSS circle element.
