Let's make a map with D3.js!

This example shows a world map using a natural Earth projection, with countries filled in light green and oceans in blue, all rendered as SVG paths. It loads geographic data from the World Atlas TopoJSON dataset via `json()`, then converts the TopoJSON features into GeoJSON using the TopoJSON `feature()` function. The map is drawn with D3’s `geoPath` and `geoNaturalEarth1` projection, and styled with CSS classes for the sphere and countries.

This example demonstrates how to create a world map using D3.js. It renders a natural Earth projection of countries as SVG paths, filled with light green and outlined with a subtle black stroke, all set against a blue sphere background. The code uses `d3.json` to load geographic data from the world-atlas TopoJSON file, then converts it to GeoJSON with `topojson.feature`. The map is drawn using `d3.geoPath` and the `geoNaturalEarth1` projection, with the sphere added as a separate path.

This example displays a world map using a natural Earth projection, with countries rendered as light green SVG paths and oceans shown as a blue sphere. The code loads geographic data from the world-atlas TopoJSON file, converts it to GeoJSON using the topojson `feature` function, and draws it with `d3.geoPath` and `d3.geoNaturalEarth1` from D3 v5. A single SVG element sized 960 by 500 hosts the visualization.

This example displays a basic world map using a natural Earth projection, with dark gray landmasses on a near-black globe sphere. The map is rendered as SVG paths generated from TopoJSON country boundaries loaded from the world-atlas package. It uses D3 v5’s `geoNaturalEarth1` projection and `geoPath` to convert geographic features into visible shapes. The code fetches the dataset with `json`, processes it via TopoJSON’s `feature` method, and appends each country path to the SVG container.

This example displays a world map using a natural Earth projection, rendering countries as filled paths with a visible ocean sphere background. The map uses TopoJSON data from the World Atlas package, which is converted to GeoJSON via `feature`. The visualization is built with D3 v5, using `geoNaturalEarth1` for the projection, `geoPath` to generate SVG path data, and `select` to append the country and sphere elements to the SVG canvas.

This example displays a world map rendered as an SVG using a natural Earth projection. D3’s `geoPath` and `geoNaturalEarth1` draw country boundaries from TopoJSON data loaded via `json`, while a blue sphere path represents the globe. The `feature` method from TopoJSON converts the world-atlas dataset into GeoJSON features, which are filled with light green and outlined with faint black strokes.

This example displays a world map using a natural Earth projection, with countries rendered as light green SVG paths with subtle black strokes. The map is drawn from TopoJSON data loaded from the visionscarto-world-atlas package, using D3 v5’s `geoPath` and `geoNaturalEarth1` projection. A blue sphere path outlines the globe’s boundary. The code specifically imports `feature` from TopoJSON to convert topologies into GeoJSON features, then binds the country data to SVG path elements. The map appears on a blank background with no additional interactive features or transitions.

Lets make a Map with D3!

This example displays a world map using a natural Earth projection, with countries rendered as light green SVG paths with black outlines. It loads geographic data from the world-atlas TopoJSON file and converts it to GeoJSON using the topojson `feature` function, then draws the map with d3.geoPath and d3.geoNaturalEarth1. The blue sphere background path is generated directly from a sphere object.
