This example shows how to create a world map with D3.js, rendering a blue sphere and green country shapes in SVG. The code uses `d3.geoNaturalEarth1` for the map projection and `d3.geoPath` to generate the country outlines from TopoJSON data. It loads the world-atlas dataset from unpkg, converts the TopoJSON to GeoJSON with `topojson.feature`, and appends paths for each country. The visualization is built with D3 v5, using promise-based `d3.json` to asynchronously fetch the geographic data.

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 creates a world map rendered as SVG using D3 v5 and TopoJSON. It loads world country boundaries from the World Atlas TopoJSON dataset, projects them with the `geoNaturalEarth1` projection, and draws each country as a filled path using `d3.geoPath`. A blue sphere background is added first, with countries shown in light green and outlined with subtle black strokes. The map displays the entire globe with country shapes accurately projected.

Let's make a map with D3.js

This example renders a world map using D3.js and TopoJSON, applying the natural Earth projection via `d3.geoNaturalEarth1` and drawing country boundaries with `d3.geoPath`. The SVG shows a blue sphere outline and light green countries with subtle black strokes. It loads country geometries from the world-atlas 110m TopoJSON dataset and converts them to GeoJSON using TopoJSON’s `feature` function. The code appends paths for the sphere and each country, demonstrating a straightforward choropleth-free geographic visualization.

Let's make a map with D3.js!

This example shows a world map rendered as an SVG, with countries filled in green and the sphere outline in blue. It uses a Natural Earth projection to display the globe. The visualization loads geographic data from the World Atlas TopoJSON file and applies D3’s `geoPath` to generate the country shapes. The code demonstrates a straightforward pipeline with `d3.json`, `topojson.feature`, and simple SVG path elements, styling the map for clear visual separation.

Let's make a map with D3.js

This example shows a geographic world map rendered as an SVG using D3.js and TopoJSON. It displays country boundaries and a blue sphere outline, with countries filled in light green and subtle black strokes. The code loads world-atlas data via D3’s `json` method and converts TopoJSON features using `topojson.feature`. It applies a natural Earth projection with `d3.geoNaturalEarth1` and generates paths via `d3.geoPath`. The visualization relies on D3 v5 and TopoJSON v3 scripts.

Let's make a map with D3.js!

This example demonstrates how to create a world map using D3.js, rendering countries as SVG paths filled with light green and a blue sphere as the globe backdrop. It employs the `d3.geoNaturalEarth1` projection and `d3.geoPath` to generate geographic shapes, while loading TopoJSON data from the world-atlas package and converting it to GeoJSON via `topojson.feature`. The map is drawn on a static 960×500 SVG canvas without interactivity.

Let's make a map with D3.js!

This example demonstrates a static world map using D3.js, rendering countries and the Earth’s sphere as SVG paths with a Natural Earth projection. It uses `d3.geoPath` with `d3.geoNaturalEarth1`, and the `topojson` library’s `feature` method to convert TopoJSON from the `world-atlas` dataset into GeoJSON features. The sphere is drawn in blue, countries in light green with black outlines, and the code loads data asynchronously via `d3.json`.
