This example displays a choropleth-style map of a country’s regions using D3.js geoMercator and geoPath projections, rendered as an SVG within a React application. The map draws region boundaries as dark strokes, fills each feature with an olive-green color, and overlays a yellow interior mesh to highlight shared borders. Data is fetched as TopoJSON from a public Gist, then converted to GeoJSON using the topojson library’s feature and mesh functions, demonstrating a complete pipeline from raw geodata to interactive map.

Let's make a map with D3.js!

This example displays a world map rendered with SVG paths, using D3.js v5 and TopoJSON. It loads geographic country boundaries from the world-atlas dataset and projects them with a Mercator projection. The code uses `d3.geoPath` and `d3.geoMercator` to generate the map, while `topojson.feature` converts the TopoJSON data into GeoJSON features. Countries appear filled in steel blue with black, semi-transparent borders, demonstrating a minimal choropleth-style base map.

Let's make a map with D3.js!

This example renders a world map using D3.js and TopoJSON. It loads the world-atlas dataset and converts its TopoJSON topology into GeoJSON features, then draws each country as an SVG path. The map uses the Mercator projection via `d3.geoMercator` and `d3.geoPath` to generate the path data. Country polygons are filled with steelblue and outlined with black strokes, displaying a basic choropleth-style world map without additional data encoding.

Making Maps:World Map with TOPOJSON Data Links

This example shows a world map with countries rendered in green and outlined in crimson, set against a blue spherical backdrop. It uses D3 v5’s `geoMercator` projection and `geoPath` to convert geographic coordinates into SVG paths. The map loads TopoJSON data from the `world-atlas` repository via `topojson.feature`, which converts the encoded country boundaries into GeoJSON for rendering.

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.

Topojson Map

This example displays a world map rendered as filled country polygons on a sphere background. It uses d3.json to load TopoJSON data from the world-atlas package, then converts it to GeoJSON features with topojson.feature. The map is drawn in SVG using d3.geoPath with a d3.geoNaturalEarth1 projection, styling countries in green and the sphere in dark blue.

World map with the world Topojson data

This example displays a world map using the Topojson world data, rendered as an SVG with a teal sphere background and white country boundaries. It employs D3.js v5’s geoEquirectangular projection and d3.geoPath to convert geographic coordinates into SVG paths. The data loads from a remote GitHub gist, and the topojson library’s feature function extracts country geometries. The map is styled via CSS classes for the sphere and individual countries.

World Map with Topojson data

This example displays a world map using TopoJSON data, rendering countries as blue-filled paths with pink strokes against a white spherical backdrop. It uses D3 v5’s `geoMercator` projection and `geoPath` to convert geographic coordinates into SVG paths, while the TopoJSON library’s `feature` method extracts country geometries from a remote JSON file. The visualization loads data asynchronously via `json` and appends each country path to the SVG canvas, demonstrating a straightforward choropleth-free baseline of global boundaries.

Let's make a map with D3.js!

This example renders a world map using D3.js and TopoJSON, displaying country boundaries as SVG paths filled with steel blue. The map uses a Mercator projection via `d3.geoMercator` and `d3.geoPath` to convert geographic coordinates into screen paths. It loads world-atlas data from unpkg, extracting country features with `topojson.feature`. The React framework is not actively used in the visible code; instead, the script directly appends paths to an SVG element.
