World map with D3.js!

World Map

This example displays a world map rendered as an SVG using D3.js v5. It uses `d3.geoNaturalEarth1` for the projection and `d3.geoPath` to draw country boundaries from a TopoJSON file loaded via `topojson.feature`. The map includes a blue sphere outline and green country shapes with strokes. The code demonstrates fundamental data binding and path generation for geographic visualization.

World Map Example

This example renders a natural Earth world map in an SVG using D3.js v5. It draws a blue sphere backdrop and then loads country boundaries from a TopoJSON file via `d3.json` and the `topojson` library’s `feature` method. The projection uses `d3.geoNaturalEarth1` with `d3.geoPath` to generate the country paths, which are filled light green with semi-transparent black strokes. The map displays static country outlines without interaction or additional data layers.

World Map Example

This example renders a world map using D3.js and TopoJSON, displaying country boundaries as SVG paths. The visualization shows a natural Earth projection of the globe, with countries filled in light green and oceans in blue, using a grayscale-style aesthetic. The code loads geographic data from the world-atlas TopoJSON file and applies `d3.geoNaturalEarth1` for projection, `d3.geoPath` for path generation, and `topojson.feature` to extract country features. A sphere outline is drawn first, followed by individual country paths appended to the SVG canvas.

Map with D3.js!

This example displays a world map rendered as an SVG, with countries filled in light green against a blue ocean background. It uses D3.js version 5 to load geographic data from the World Atlas TopoJSON file and convert it to GeoJSON features. The map is drawn with the `d3.geoPath` and `d3.geoNaturalEarth1` projection, while `topojson.feature` extracts country boundaries from the dataset. The code appends paths for the sphere and each country, applying basic styling from an external CSS file.

World Map

This example renders a natural Earth projection world map as an SVG, showing country boundaries in black with red outlines against a light blue sphere. It uses D3 v5’s `geoNaturalEarth1` projection and `geoPath` to draw the sphere and landmasses, with TopoJSON’s `feature` method converting world-atlas data (110m resolution) into GeoJSON. The map is generated asynchronously, fetching the TopoJSON from a CDN and appending each country path to the SVG.

Let's make a map with D3.js!

This example renders a world map using the Natural Earth projection via D3.js. A light green SVG path for each country is drawn over a blue spherical backdrop, with black strokes at low opacity for boundaries. The code uses `d3.geoPath` with the `geoNaturalEarth1` projection, loads geographic data from the `world-atlas` 110m JSON dataset, and constructs country features using the `topojson` library. The visualization is entirely SVG-based.

World Map

This example displays a natural Earth projection world map using SVG paths generated with `d3.geoPath` and `d3.geoNaturalEarth1`. It renders the globe’s sphere in aqua and country boundaries as coral polygons with black strokes, loaded from a TopoJSON file via `topojson.feature`. Hovering a country turns it white. The code imports from D3 v5 modules and fetches world-atlas data from unpkg.
