This example demonstrates how to create a world map using D3.js, displaying countries as light green shapes with faint black outlines on an SVG canvas. The map uses a conic conformal projection defined through D3's `geoConicConformal` and `geoPath` APIs. It loads geographic boundary data from the world-atlas TopoJSON source, processes it with the `topojson` library’s `feature` function, and renders each country as an SVG path. The visualization also generates a background path, with a commented-out sphere class suggesting an optional ocean fill.

Let's make a map with D3.js!

This example demonstrates how to construct a world map using D3.js, rendering individual countries as SVG paths with light green fills over a blue spherical background. The visualization loads geographic data from the world-atlas TopoJSON dataset and applies a geoAzimuthalEquidistant projection, clipped to a rectangular viewport using geoClipRectangle. It relies on d3.geoPath to generate the SVG paths and topojson.feature to convert the TopoJSON topology into GeoJSON features for display.

Let's make a map with D3.js!

This example demonstrates how to create a world map using D3.js, rendering countries as SVG paths filled with light green and a blue sphere as the globe backdrop. It employs the `d3.geoNaturalEarth1` projection and `d3.geoPath` to generate geographic shapes, while loading TopoJSON data from the world-atlas package and converting it to GeoJSON via `topojson.feature`. The map is drawn on a static 960×500 SVG canvas without interactivity.

Let's make a map with D3.js!

This example demonstrates how to create a world map using D3.js, displaying countries as light green SVG paths on a blue sphere with black outlines. It uses the `d3.geoNaturalEarth1` projection and `d3.geoPath` to render geographic features, with country boundaries derived from the TopoJSON world-atlas dataset. The code loads geographic data asynchronously via `d3.json`, converts TopoJSON to GeoJSON using the `topojson.feature` method, and appends each country path to the SVG canvas. The map is rendered entirely with SVG elements in a minimalist style.

Let's make a map with D3.js!

This example displays a world map of countries filled with light green and outlined in black, set against a dark blue sphere representing the globe. The visualization uses D3.js v5 and the topojson library to load country boundaries from the world-atlas dataset, then renders them as SVG paths. The code applies a geoNaturalEarth1 projection through d3.geoPath, first drawing the sphere background and then appending a path for each country feature.

Let's make a map with D3.js

This example shows a world map rendered as SVG paths with light green countries outlined in black. It uses D3.js v5 to load GeoJSON data from the World Atlas TopoJSON dataset via `topojson.feature`, then projects the coordinates using the `geoConicConformal` projection and draws the paths with `geoPath`. The code employs D3's `json` loader for the remote file and appends each country path to an SVG container.

Let's make a map with D3.js!

This example shows a world map rendered as an SVG, with countries filled in light green against a blue spherical backdrop. It uses D3.js version 5 and the TopoJSON library to load and convert world-atlas data (110m resolution) into GeoJSON features. The map is drawn with `d3.geoPath` and a natural Earth projection (`d3.geoNaturalEarth1`), while a separate path renders the globe’s sphere outline. Country boundaries appear with a subtle black stroke, and the map updates once the external JSON data loads.

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 demonstrates how to create a simple world map using D3.js, displaying countries as light green polygons against a blue sphere background. The visualization uses the `geoNaturalEarth1` projection and `geoPath` to generate SVG paths from TopoJSON data loaded from the world-atlas dataset. The code relies on D3 v5 and the topojson library, specifically using the `feature` function to convert TopoJSON to GeoJSON. The map is rendered entirely with SVG elements, with the sphere outline drawn first, followed by the country boundaries.
