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.

This example displays a world map using an orthographic projection, rendering countries as light-green SVG paths against a dark blue background. The map is built entirely with D3.js v5 and TopoJSON, loading geographic data from the world-atlas dataset. The code uses `d3.geoOrthographic` and `d3.geoPath` to project and trace country boundaries, while `topojson.feature` extracts the geometries for rendering.

This example renders an orthographic globe using D3.js and TopoJSON, drawing country boundaries as green SVG paths with white strokes over a sphere background. It loads world geography from the world-atlas dataset, converts TopoJSON features via `topojson.feature`, and projects them with `d3.geoOrthographic` and `d3.geoPath`. The map is static, with no rotation or interaction, and displays all countries at a 110m resolution.

This example renders a world map of countries using D3.js and TopoJSON. It loads geographic data from the world-atlas dataset and displays country boundaries as SVG paths. The visualization uses `d3.geoMercator` for the projection and `d3.geoPath` to generate the path data from the TopoJSON features. Each country is appended as a `path` element to an SVG canvas sized 960 by 500 pixels.

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.

The example demonstrates how to create a world map visualization using D3.js, rendering geographic features as SVG elements. It shows country boundaries and a styled ocean sphere, with countries colored light green and outlined with subtle black strokes. The code loads GeoJSON data via `d3.json` from the world-atlas TopoJSON dataset, converts it using the TopoJSON client library, and projects the map with `d3.geoPath` and a geographic projection. The visualization includes a blue sphere background and depends on D3 v5 and the `topojson` library for data processing.

Let's make a map with D3.js!

This example displays an orthographic map of the world, rendered as a blue sphere with grey country outlines. It uses D3’s `geoOrthographic` projection and `geoPath` to draw the sphere and country boundaries, pulling geographic data from the `world-atlas` TopoJSON dataset via `topojson.feature`. The SVG output includes a styled sphere fill and country paths, with interactive rotation not implemented in the shown code.

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.
