This example demonstrates seamless transitions between dozens of geographic map projections, cycling automatically through options like Aitoff, Mercator, and Robinson. A dropdown menu also lets users manually select any projection. The visualization uses d3.geo.path with the geo.projection plugin to render world landmasses from TopoJSON data, along with graticules and sphere outlines. The code interpolates between projections using d3's transition system, updating the path generator's projection on a timer to animate the morphing effect smoothly in SVG.

These projections are available in the geo.projection plugin.

Projection Transitions

Projection Transitions showcases a rotating sequence of over 40 map projections, including Aitoff, Mercator, and Winkel Tripel. The visualization draws world land boundaries from TopoJSON and overlays a geographic graticule, rendering each projection with d3.geo.path. A dropdown menu allows manual selection, while an automatic timer cycles through projections every 1.5 seconds. The code uses the d3.geo.projection plugin and applies SVG animations to transition smoothly between geographic coordinate systems.

Projection Transitions

A dropdown menu animates between 40+ map projections, swapping the rendered world map and graticule every 1.5 seconds. The visualization uses the `d3.geo.projection` plugin’s various projection constructors (e.g., `d3.geo.aitoff`, `d3.geo.robinson`) and renders land polygons via `d3.geo.path` with SVG paths, including a graticule overlay. The world-110m GeoJSON source feeds `topojson.feature` to build the land shapes. Selecting a projection from the menu triggers an animated transition between projections.

Projection Transitions

A drop-down menu and an auto-advancing timer cycle through dozens of map projections, each rendered over a world map with a graticule and sphere outline. The example shows how D3’s `d3.geo.path` and the `d3.geo.projection` plugin smoothly interpolate between projections using the `transition` API, with land from TopoJSON. A menu allows manual selection, while a periodic random selection demonstrates animated morphing between projections.

d3v5 - Selective Projection Map

This example visualizes a world map with a dropdown menu to switch between over 40 different geospatial projections, including Miller, Mercator, and Robinson. The map is rendered as SVG using d3.geoPath, while the projection options are defined with d3-geo-projection methods like d3.geoMercator and d3.geoMiller. World coastlines come from a GeoJSON file, and a graticule and sphere outline are added to each view.

Globe to Map transition

A world map transitions between two geographic projections: an interactive 3D globe and a flat, equirectangular map. Users rotate the globe by dragging, and a single click triggers a smooth 7.5-second animation that interpolates between the orthographic and equirectangular projections, with the map always cut along the antimeridian for an unrolling effect. Double-clicking a country reverses the transition. Built with D3 v3 and TopoJSON, it uses `d3.geo.orthographic()`, `d3.geo.equirectangular()`, `d3.geo.path()`, and `d3.transition()` for tweening the projection, rendering country boundaries from a 110m world dataset in SVG with hover tooltips.

Globe to Map transition

This interactive visualization demonstrates a smooth animated transition between two geographic projections of the same world map. A slowly rotating orthographic globe morphs into a flat equirectangular projection when a country is clicked, with a double-click on any country triggering the reverse transformation. The example highlights the shortest path between these two projection states. The code uses d3.v3, specifically the `d3.geo.orthographic()` and `d3.geo.equirectangular()` projections, along with the `d3.geo.path()` for generating SVG paths. Country boundaries come from a TopoJSON file, and country names are loaded from a TSV file.

go_ndm_01

This example demonstrates smooth transitions between two map projections, Equirectangular and Natural Earth, with a red dot marking the origin [0,0] on each projection. The visualization cycles through projections every 1.5 seconds with a 750-millisecond tween, combining animated morphing of map paths with graticule and land outlines from a world-110m GeoJSON dataset. Using D3 v4, it employs `d3.geoPath`, `d3.geoGraticule`, and a custom projection tween based on `attrTween`, along with a dropdown menu to manually switch projections and pause the automatic rotation.

Globe to Map transition

A world map transitions between an orthographic globe and an equirectangular projection. The globe rotates via a D3 drag behavior, and clicking a country triggers a path-by-path transition to the flat map, while double-clicking returns to the globe. The visualization uses D3 v3 with `d3.geo.orthographic`, `d3.geo.equirectangular`, and `d3.geo.path` to render TopoJSON country boundaries as SVG paths, with CSS-based tooltips and hover highlighting.
