This example renders a world map using D3.js and topojson, displaying country boundaries as light green shapes on a blue sphere. The visualization loads geographic data from the world-atlas TopoJSON file and converts it to GeoJSON features using the topojson `feature` function. D3’s `geoNaturalEarth1` projection and `geoPath` generator draw each country as an SVG path, with a separate path for the global sphere. The code uses the v5 API with imported functions from the d3 module, and styling applies stroke opacity to delineate borders.

Let's make a MAP with D3.js!

This example displays a world map rendered as an SVG, with countries filled in light green and the ocean depicted as a sky-blue sphere. It uses D3 v5 and TopoJSON to load world-atlas data at 110m resolution, then applies the `d3.geoNaturalEarth1` projection and `d3.geoPath` to generate country boundaries. The map also draws a background sphere path, and country strokes are semi-transparent black. The code relies on `topojson.feature` to convert TopoJSON topology into GeoJSON features for rendering.

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 against a sky-blue sphere background. It uses the `geoNaturalEarth1` projection and `geoPath` to draw country boundaries from TopoJSON data loaded from the world-atlas package. The code fetches the countries-110m.json file, converts it to GeoJSON with `feature`, and appends each path to an SVG element. Both D3 v5 and TopoJSON are loaded via CDN, and the visualization is built with a React starter setup.

Let's make a map with D3.js!

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.

Let's make a map with D3.js!

This example renders a world map using D3.js and TopoJSON. It shows a blue sphere representing the Earth and draws country boundaries in light green with black strokes. The map uses the Natural Earth projection and data from the World Atlas TopoJSON dataset. The code leverages d3.geoPath, d3.geoNaturalEarth1, and the topojson feature function to convert geographic data into SVG paths.

Let's make a map with D3.js

This example renders a world map using D3.js and TopoJSON, applying the natural Earth projection via `d3.geoNaturalEarth1` and drawing country boundaries with `d3.geoPath`. The SVG shows a blue sphere outline and light green countries with subtle black strokes. It loads country geometries from the world-atlas 110m TopoJSON dataset and converts them to GeoJSON using TopoJSON’s `feature` function. The code appends paths for the sphere and each country, demonstrating a straightforward choropleth-free geographic visualization.

Let's make a map with D3.js!

This example demonstrates how to create a world map using D3.js v5, displaying country boundaries as light green polygons on a blue sphere. It loads geographic data from the world-atlas TopoJSON dataset and renders it as SVG using `d3.geoPath` with the `geoNaturalEarth1` projection. The code processes the TopoJSON through the `topojson.feature` API and applies a `geoPath` generator to draw each country outline with stroke opacity styling.

Let's make a map with D3.js!

This example demonstrates how to create a world map using D3.js and TopoJSON. It renders country boundaries as green SVG paths with thin black strokes on a dark blue background, using a Mercator projection. The visualization loads geographic data from the world-atlas TopoJSON file and converts it to GeoJSON features with the `feature` function. The code uses `d3.geoMercator` and `d3.geoPath` to project the map coordinates and generate the path data.

Let's make a map with D3.js!

This example shows a world map rendered as an SVG, with countries filled in light green and the globe as a blue sphere. It demonstrates loading geographic data from a TopoJSON file via `d3.json` and converting it to GeoJSON features using the `feature` function from the TopoJSON library. The map projection and path generation are handled by `d3.geoNaturalEarth1` and `d3.geoPath`, which draw the country boundaries and the sphere outline. The code uses D3 v5 and relies on the world-atlas dataset at 110m resolution.
