This example visualizes world country boundaries as filled polygons on a natural Earth projection, rendered as SVG. It uses D3.js v5 with `d3.geoNaturalEarth1` for projection, `d3.geoPath` to generate the path data, and `topojson.feature` to convert TopoJSON country data from the world-atlas dataset. The ocean sphere is drawn first, followed by country shapes, with distinct fill colors for each. The map displays 110m-resolution country outlines loaded asynchronously via a JSON promise.

Let's make a map with D3.js!

This example visualizes the world’s countries as filled polygons on a natural Earth projection, with oceans rendered in blue and landmasses in light green. It uses D3.js v5’s `geoNaturalEarth1` projection and `geoPath` to generate SVG paths, while TopoJSON’s `feature` function extracts country boundaries from a 110m world-atlas GeoJSON dataset. The code draws a sphere background and then overlays each country’s path, applying thin black strokes for borders.

Let's make a MAP with D3.js!

This example displays a world map rendered as an SVG, with countries filled in light green and the ocean depicted as a sky-blue sphere. It uses D3 v5 and TopoJSON to load world-atlas data at 110m resolution, then applies the `d3.geoNaturalEarth1` projection and `d3.geoPath` to generate country boundaries. The map also draws a background sphere path, and country strokes are semi-transparent black. The code relies on `topojson.feature` to convert TopoJSON topology into GeoJSON features for rendering.

Let's make a map with D3.js!

This example displays a world map with countries filled in light green against a dark blue ocean sphere, projected using the Natural Earth projection. The visualization is built with D3.js v5, using `d3.geoNaturalEarth1` for the projection and `d3.geoPath` to generate country boundaries from the world-atlas TopoJSON dataset. The `topojson.feature` library processes geographic features, and SVG paths render each country. The map is presented within an empty SVG canvas, with the sphere and country paths styled via CSS classes.

Let's make a map with D3.js

This example shows a world map rendered as an SVG using D3.js, with countries filled in light green against a sky-blue sphere background. It uses the `geoNaturalEarth1` projection and `geoPath` to draw country boundaries from TopoJSON data loaded from the world-atlas package. The code fetches the countries-110m.json file, converts it to GeoJSON with `feature`, and appends each path to an SVG element. Both D3 v5 and TopoJSON are loaded via CDN, and the visualization is built with a React starter setup.

Lets Make a map with D3.js

This example visualizes world countries as a static map using a natural Earth projection. The map renders countries in light green with subtle black strokes against a dark blue sphere, providing a clear geographic overview. The code uses D3 v5’s `geoNaturalEarth1` projection and `geoPath` to draw SVG paths, while TopoJSON’s `feature` extracts country boundaries from a world-atlas dataset. Country shapes are appended to an SVG container, with styling applied via CSS classes for sphere and country paths.

Let's make a map with D3.js!

This example displays a world map using a natural Earth projection, rendering countries as filled paths with a visible ocean sphere background. The map uses TopoJSON data from the World Atlas package, which is converted to GeoJSON via `feature`. The visualization is built with D3 v5, using `geoNaturalEarth1` for the projection, `geoPath` to generate SVG path data, and `select` to append the country and sphere elements to the SVG canvas.

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.
