This example shows a world map rendered on interactive 3D objects—a plane and a sphere—inside an A-Frame virtual reality scene, with the map rotating continuously over time. The geographic data is drawn to a 2D canvas using `d3.geoEquirectangular` for the projection, `d3.geoPath` for generating paths, and `d3.geoGraticule` for the grid lines. A `d3.timer` controls the animation loop, while an A-Frame component (`draw-canvas`) updates the canvas texture on the 3D entities. The map geojson includes country polygons from a natural earth dataset.

Zoom and Rotating (Reprojecting)

This example demonstrates a dynamic equirectangular world map that is rendered onto a canvas and then applied as a texture to both a plane and a sphere in a 3D A-Frame scene, allowing for zoom and rotation. The map, sourced from a GeoJSON file, uses `d3.geoEquirectangular` projection and a `d3.geoPath` generator to draw graticules and country boundaries. A `d3.timer` drives continuous redraws to the canvas, while the A-Frame `draw-canvas` component integrates it into the virtual environment, with the sphere and camera controls enabling interactive reprojection.

Zoom and Rotating (Reprojecting)

This example shows a continuously rotating and reprojecting world map rendered onto a canvas texture inside a 3D A-Frame scene. It demonstrates how geographic data can be integrated with WebVR-style environments, drawing country polygons, graticules, and the sphere outline using D3 v4’s `d3.geoMercator` projection, `d3.geoPath`, and `d3.geoGraticule`. The animation runs via `d3.timer`, updating the projection rotation each frame and clearing/redrawing the canvas context. The map uses GeoJSON world land data loaded from `land.geojson` and displays alongside a simple A-Frame box primitive.

Zoom and Rotating (Reprojecting)

This example demonstrates interactive zooming and rotating of a world map through a 3D scene, allowing for dynamic reprojection of the geography. The visualization combines D3.js for map rendering with A-Frame, a WebVR framework, to create a three-dimensional environment where the map can be manipulated. It uses the Datamaps library to render the world map with custom data fills and overlays like arcs and bubbles, while A-Frame's `a-scene` handles the 3D elements and camera controls. The map is rendered onto a canvas element, which is then used as a material on 3D objects within the scene.

Zoom and Rotating (Reprojecting)

This example demonstrates map reprojection with zoom and rotation using D3 v4 and canvas rendering. It displays geographic data from `ne_110m_admin_0_sovereignty.geojson` and a graticule, drawn with `d3.geoPath` and a `d3.geoEquirectangular` projection that rotates over time via `d3.timer`. The scene is embedded in an A-Frame 0.5.0 environment with multiple canvas textures applied to 3D entities, including a sphere and plane, using the `draw-canvas` component.

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 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.

World Map

This example presents an interactive orthographic world map that automatically rotates over time. The visualization uses D3’s `geoOrthographic` projection and `geoPath` to render continents and graticules as SVG, with country data from the world-atlas TopoJSON and TSV files. Users can zoom and pan the globe via `d3.zoom`, while hovering over landmasses highlights them in yellow. The rotation is driven by a `d3.timer` that continuously updates the projection’s rotation.

Document

This example shows an interactive world map rendered on a Canvas element, with a red landmass silhouette. It demonstrates how to synchronize a custom map projection with the D3 zoom behavior, so that panning and zooming directly manipulate the projection’s translate and scale values. The code uses `d3.geoMercator` and `d3.geoPath` to draw the map, while a topojson mesh is fetched from a remote URL and rendered as filled paths. A zoom handler clears and redraws the canvas on each transform, and the projection is initially fitted to a simple LineString feature using `fitExtent`.
