This example displays a world map with country boundaries and a graticule overlay, rendered as SVG using D3.js v5. It shows countries as light green polygons with subtle black strokes against a blue sphere background. The code uses `d3.geoNaturalEarth1()` for projection, `d3.geoPath()` for path generation, and TopoJSON’s `feature` method to convert World Atlas TopoJSON data (from unpkg) into GeoJSON. A graticule is drawn with `geoGraticule`, and the sphere outline is generated via `pathGenerator({type: 'Sphere'})`.

Let's make a map with D3.js!

This example displays a world map rendered as an SVG, with countries filled in light green against a blue spherical backdrop. It uses D3 v5 and TopoJSON to load world-atlas data, then applies a natural Earth projection via `d3.geoNaturalEarth1` and traces country boundaries with `d3.geoPath`. The code also draws a background sphere path to represent the globe.

Let's make a map with D3.js!

This example shows a world map rendered as an SVG, with countries filled in light green against a blue spherical backdrop. It uses D3.js version 5 and the TopoJSON library to load and convert world-atlas data (110m resolution) into GeoJSON features. The map is drawn with `d3.geoPath` and a natural Earth projection (`d3.geoNaturalEarth1`), while a separate path renders the globe’s sphere outline. Country boundaries appear with a subtle black stroke, and the map updates once the external JSON data loads.

Let's make a map with D3.js!

This example shows a world map rendered as an SVG, with countries filled in light green and the globe as a blue sphere. It demonstrates loading geographic data from a TopoJSON file via `d3.json` and converting it to GeoJSON features using the `feature` function from the TopoJSON library. The map projection and path generation are handled by `d3.geoNaturalEarth1` and `d3.geoPath`, which draw the country boundaries and the sphere outline. The code uses D3 v5 and relies on the world-atlas dataset at 110m resolution.

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 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 shows a world map rendered as SVG, with countries filled in light green and oceans depicted as a blue sphere. It loads GeoJSON country boundaries from the World Atlas TopoJSON dataset via `d3.json` and converts them using the TopoJSON `feature` function. The map is drawn with `d3.geoPath` and a `d3.geoNaturalEarth1` projection, adding a background sphere path for the ocean. Using D3 v5 and SVG, it demonstrates a straightforward choropleth-style basemap without interactivity.

Let's make a map with D3.js!

This example demonstrates how to create a world map using D3.js v5, rendering country boundaries as light green SVG paths on a blue sphere. It shows a natural Earth projection with subtle black stroke outlines for each country. The visualization loads GeoJSON data from the world-atlas TopoJSON file using `d3.json`, then converts it to geographic features with `topojson.feature`. The code applies `d3.geoPath` with a `geoNaturalEarth1` projection to draw both the sphere background and individual country shapes onto the SVG canvas.
