This example shows a world map rendered as a three-dimensional globe using an orthographic projection. The sphere is filled dark blue, while country boundaries appear in light green with subtle black strokes, all drawn as SVG paths. The code uses d3.geoOrthographic and d3.geoPath to project and trace the map, with data loaded from the world-atlas TopoJSON file. TopoJSON’s feature method extracts country geometries, and each is appended as an SVG path inside a fixed 960×500 canvas.

Let's make a map with D3.js!

This example shows a simple orthographic world map rendered as an SVG, with countries filled in light green and a blue sphere representing the globe. It uses D3 v5’s `geoOrthographic` projection and `geoPath` to draw country boundaries from TopoJSON data loaded from the world-atlas dataset. The code appends a sphere path, then fetches the TopoJSON file, converts it to GeoJSON with the `feature` function from the topojson library, and binds the resulting country features to SVG paths.

Let's make a Map!

This example displays a world map of countries as light green shapes against a dark blue spherical background, using a Mercator projection. It loads geographic data from the world-atlas TopoJSON dataset and renders it as SVG paths with d3.geoPath. The code employs d3-geo projections, topojson.feature for extraction, and a select-all data join to bind country features to path elements.

Let's make a map?!

This example shows how to create a simple world map by loading TopoJSON country boundaries and rendering them as filled paths. The code uses d3.json to fetch the world-atlas dataset, topojson.feature to convert it to GeoJSON, and d3.geoMercator with d3.geoPath to project and draw the countries. All shapes are appended as SVG path elements, styled with green fills and black strokes.

Let's make a map with D3.js

This example displays a world map rendered as an SVG, with countries filled in green against a dark blue spherical backdrop. It fetches country boundaries from a TopoJSON file via the world-atlas dataset, then projects them using the Hufnagel projection from `d3-geo-projection`. The code builds paths with `d3.geoPath` and `d3.json`, styling the sphere and landmasses through CSS classes. It relies on D3 v5, TopoJSON’s `feature` method, and demonstrates a compact, data-driven mapping workflow.

Let's make a map with D3.js!

This example creates a world map rendered as SVG using D3 v5 and TopoJSON. It loads world country boundaries from the World Atlas TopoJSON dataset, projects them with the `geoNaturalEarth1` projection, and draws each country as a filled path using `d3.geoPath`. A blue sphere background is added first, with countries shown in light green and outlined with subtle black strokes. The map displays the entire globe with country shapes accurately projected.

Let's make a MAP with D3.js

This example shows a world map rendered in an SVG using D3.js with an orthographic projection, displaying countries as light-green paths with subtle black strokes against a dark blue sphere background. The visualization loads geographic data from the world-atlas TopoJSON file (countries-110m.json) and converts it to GeoJSON using the topojson `feature` function. The code specifically uses D3 v5 APIs including `d3.geoOrthographic`, `d3.geoPath`, and `d3.json` to project and draw the map, with commented alternatives for other projections like Mercator and Natural Earth.

Let's make a map with D3.js!

This example renders a world map showing country boundaries as light green filled paths on a steel blue sphere, using a geographic equal Earth projection. The map is drawn entirely as SVG with D3 v5 and TopoJSON, loading the world-atlas 110m dataset from unpkg. The code defines a path generator via d3.geoPath and d3.geoEqualEarth, appends a spherical outline, then converts the TopoJSON topology to GeoJSON features using topojson.feature before binding them to path elements.

Let's make a map with D3.js!

This example displays a world map using an orthographic projection, rendering countries as light-green SVG paths with dark strokes. It loads geographic data from a TopoJSON world-atlas file via `d3.json`, then converts it to GeoJSON using `topojson.feature`. The map is drawn with `d3.geoPath` and `d3.geoOrthographic`, projecting the spherical landmasses onto a flat plane. The dark blue background and minimal styling emphasize the Earth’s curved shape, creating a simple globe-like visualization.
