This example displays a world map in D3.js using the Natural Earth projection (geoNaturalEarth1) and draws country boundaries as SVG paths. It begins by rendering a blue sphere backdrop, then loads geographical data from the world-atlas package via a JSON request. The topojson library’s feature function extracts country geometries, which are then projected and drawn as light green filled paths with subtle black strokes using d3.geoPath. The map is rendered entirely as vector SVG elements, demonstrating a basic choropleth setup with static styling.

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.

Let's make a map with D3.js!

This example demonstrates how to create a world map using D3.js, rendering countries with a natural Earth projection. It displays a blue sphere background and green country shapes with subtle black borders. The code uses D3's `geoNaturalEarth1` projection and `geoPath` to generate SVG paths, while the TopoJSON library's `feature` function extracts country boundaries from a world-atlas dataset. The visualization loads geospatial data from a remote JSON file and renders the map entirely as scalable vector graphics.

Let's make a map with D3.js!

This example shows a world map rendered as SVG, with countries filled in light green against a blue sphere, using a natural Earth projection to display the globe. The code loads GeoJSON country boundaries from the world-atlas TopoJSON dataset and converts them using the `feature` function from topojson. D3’s `geoPath` and `geoNaturalEarth1` projection generate the geographic paths, while a separate path outlines the spherical backdrop. The visualization is minimal, focusing on a clean, interactive-free display of global landmasses.

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 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.

Let's make a map with D3.js!

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.
