Let's make a map with D3.js

This example displays a world map using a natural Earth projection, with countries rendered as light green SVG paths and oceans shown as a blue sphere. The code loads geographic data from the world-atlas TopoJSON file, converts it to GeoJSON using the topojson `feature` function, and draws it with `d3.geoPath` and `d3.geoNaturalEarth1` from D3 v5. A single SVG element sized 960 by 500 hosts the visualization.

This example demonstrates how to create a world map using D3.js. It renders a natural Earth projection of countries as SVG paths, filled with light green and outlined with a subtle black stroke, all set against a blue sphere background. The code uses `d3.json` to load geographic data from the world-atlas TopoJSON file, then converts it to GeoJSON with `topojson.feature`. The map is drawn using `d3.geoPath` and the `geoNaturalEarth1` projection, with the sphere added as a separate path.

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.

This example shows a world map rendered as an SVG using D3.js with a natural Earth projection. The map displays country boundaries in light green with subtle black strokes against a blue sphere background. It loads GeoJSON data from the world-atlas TopoJSON dataset and converts it using topojson.feature. The visualization demonstrates D3’s geoPath generator to project geographic coordinates, with selectable projection types commented in the code for experimentation.

Let's make a map with D3.js!

This example demonstrates a basic world map visualization using D3.js. It renders the Earth’s landmasses as green shapes on a blue sea, with country borders outlined in black, using a natural Earth projection. The code loads GeoJSON data from the `world-atlas` package and projects it with `d3.geoPath` and `d3.geoNaturalEarth1`. It also uses TopoJSON’s `feature` function to extract country boundaries, with all graphics drawn as SVG paths.

This example displays a world map using a natural Earth projection, with countries rendered as light green SVG paths with subtle black strokes. The map is drawn from TopoJSON data loaded from the visionscarto-world-atlas package, using D3 v5’s `geoPath` and `geoNaturalEarth1` projection. A blue sphere path outlines the globe’s boundary. The code specifically imports `feature` from TopoJSON to convert topologies into GeoJSON features, then binds the country data to SVG path elements. The map appears on a blank background with no additional interactive features or transitions.

This example displays a world map with countries rendered as light green SVG paths on a blue sphere, using a natural Earth projection. The code loads geographic data from the world-atlas TopoJSON dataset and converts it to GeoJSON with topojson’s `feature` method. It builds the map with d3’s `geoPath` and `geoNaturalEarth1` projection, appending country paths and a sphere outline to the SVG canvas.
