Let's make a map with D3.js!

This example displays a world map of countries and oceans using a natural Earth projection, with landmasses filled in light green and the surrounding sphere in blue. It loads geographic data from the World Atlas TopoJSON file, converts it to GeoJSON features with `topojson.feature`, and renders paths via `d3.geoPath` and `d3.geoNaturalEarth1`. All elements are drawn as SVG paths, with a distinct path for the sphere outline and separate country paths styled through CSS.

Choropleth Map

This choropleth map colors countries by their economy category using a sequential spectral color scale. It renders world geography as SVG paths via the `d3.geoPath` and `d3.geoNaturalEarth1` projection, with zoom support through `d3.zoom`. Country names and values appear as tooltips, and a custom `colorLegend` component displays the ordinal scale. The data is loaded from a TopoJSON world atlas and a TSV mapping country IDs to metadata. Hovering highlights countries in red.

Let's make a map with D3.js!

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.
