Let's make a map with D3.js!

This example shows a world map rendered as an SVG, featuring a blue sphere background and light green country outlines. It demonstrates a basic D3.js geographic visualization using `d3.geoNaturalEarth1` for the projection and `d3.geoPath` to generate path data for the sphere. The map loads TopoJSON data from a GitHub-hosted `.json` file via `d3.json` and the `topojson` library's `feature` module, though the country data is only logged to the console rather than drawn. The code imports specific D3 functions (`select`, `json`, `geoPath`, `geoNaturalEarth1`) and relies on v5 syntax, with CSS applying fill and stroke styling to the sphere and country paths.

This example renders a world map with D3.js, displaying country boundaries and a blue sphere as the base layer. It uses the `geoNaturalEarth1` projection and `d3.geoPath` to generate SVG paths from TopoJSON data loaded from the world-atlas dataset. The visualization demonstrates a simple two-step workflow: drawing the sphere outline first, then fetching and appending each country's path via `topojson.feature`. The map is styled with CSS, using a light green fill for countries and a dark blue ocean, with a clean, minimal aesthetic.

This example shows a world map rendered as an SVG using D3.js, with countries filled in light green and oceans in blue. It uses the `geoNaturalEarth1` projection and `geoPath` to draw geographic features, while `topojson.feature` converts TopoJSON country boundaries from the world-atlas dataset. The map’s sphere outline and country paths are appended to the SVG, with styling applied via CSS classes. The code loads geographic data asynchronously using `json` from D3 v5.

This example builds an interactive SVG map of the world using D3.js v5 and the topojson library. It renders a natural Earth projection with blue oceans and light green countries, using data from the world-atlas GeoJSON file. The code employs `d3.geoPath` and `d3.geoNaturalEarth1` to project and draw geographic features, with `topojson.feature` converting the TopoJSON source into usable polygons. Each country appears as a path with a subtle black stroke.

This example visualizes a world map using a natural Earth projection, with countries rendered as green SVG paths against a blue sphere background. It loads geographic data from the World Atlas TopoJSON file and converts it to GeoJSON with `topojson.feature`. The visualization uses D3 v5’s `d3.geoPath` and `d3.geoNaturalEarth1` to project and draw the map, while CSS styles the sphere and country boundaries.

This example shows a world map rendered as a simple SVG visualization. It draws a blue sphere as the globe backdrop and then overlays individual country paths in light green with thin black strokes. The map uses a natural Earth projection and loads geographic data from the World Atlas TopoJSON dataset. The code employs `d3.geoPath` with `d3.geoNaturalEarth1` for projection, and uses `topojson.feature` to convert TopoJSON country boundaries into GeoJSON for rendering. All map elements are drawn as SVG paths inside a 960×500 viewport.

This example shows a natural Earth projection of the world, rendered as a blue sphere with no country boundaries loaded yet. The visualization uses D3 v5’s `geoNaturalEarth1` projection and `geoPath` to draw the sphere outline, while `topojson.feature` is called on an external GeoJSON file fetched via `d3.json`. The SVG canvas is 960 by 500 pixels, with the sphere filled in blue and CSS classes prepared for future country styling. The code’s console logs the fetched data but does not yet display it on the map.
