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.

Topojson World Map

This example renders a world map using a natural Earth projection, displaying countries as filled polygons on a light blue sphere. The visualization loads geographic data from the world-atlas TopoJSON file and converts it to GeoJSON features using `topojson.feature`. It draws the map with SVG paths generated by `d3.geoPath` and `d3.geoNaturalEarth1`, styling the sphere and countries via CSS classes for a clear, colorful presentation.

world map with the world Topojson data

This example displays a world map using D3.js version 5 and TopoJSON data from the world-atlas dataset. The visualization projects geographic country boundaries onto a natural Earth projection within an SVG container, with a light blue sphere background and teal country fills. The code imports geoNaturalEarth1 and geoPath for projection and path generation, and applies the feature function from topojson to convert country data into GeoJSON features. Red strokes with low opacity outline the countries, creating a distinct visual separation against the pastel background.

Topojson World Map

This example displays a world map in the Natural Earth projection, rendering countries as green polygons with a blue spherical background. It visualizes the topojson-format country boundaries from the world-atlas dataset. The code uses `d3.geoPath` with the `geoNaturalEarth1` projection to generate SVG paths, while the `topojson` library’s `feature` function converts the topojson data into GeoJSON features.

TopoJSON

This visualization displays a world map rendered as a sphere using the TopoJSON format. The map shows country boundaries in blue with no fill, projected using the geoEqualEarth projection. The code loads geographic data from a gist, converts TopoJSON to GeoJSON using topojson’s `feature` function, and renders paths with d3’s `geoPath`, all within a React component drawing to SVG.

Topojson World Map

This visualization displays a world map using a Natural Earth projection, rendering continents and countries as filled SVG paths with a blue ocean backdrop. It loads geographic data from the world-atlas TopoJSON file and converts it to GeoJSON using `topojson.feature`. The map applies `d3.geoNaturalEarth1` for projection and `d3.geoPath` to generate the country outlines, with each country filled in green and stroked with a subtle black border.

Map

This example displays a world map using a natural Earth projection, with countries shown as light green shapes against a dark blue sphere background. The visualization is rendered as SVG paths derived from TopoJSON data loaded from the world-atlas package, with each country’s boundaries drawn using D3’s geoPath and geoNaturalEarth1 projection. The code utilizes D3 v6 for data binding and selection, while TopoJSON’s feature function converts the encoded topology into GeoJSON features for rendering.

Let's make a map with D3.js!

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.

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.
