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.

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.

This example renders a world map showing country boundaries as light green filled paths on a steel blue sphere, using a geographic equal Earth projection. The map is drawn entirely as SVG with D3 v5 and TopoJSON, loading the world-atlas 110m dataset from unpkg. The code defines a path generator via d3.geoPath and d3.geoEqualEarth, appends a spherical outline, then converts the TopoJSON topology to GeoJSON features using topojson.feature before binding them to path elements.

This example shows a world map rendered with D3.js using the geoEqualEarth projection, with countries filled in green and a blue sphere background. It demonstrates geographic data visualization by loading the world-atlas TopoJSON dataset and converting it to GeoJSON features via topojson.feature. The map uses d3.geoPath with the projection to draw SVG paths. The code also imports additional projections like geoMercator and geoOrthographic, though only equal-earth is applied here.

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.

This example displays a world map rendered as SVG paths, with countries filled in light green against a dark blue sphere background. It loads geographic data from the world-atlas TopoJSON dataset and converts it to GeoJSON using the `feature` function from topojson. The map projects coordinates with `geoNaturalEarth1` and draws each country boundary via `d3.geoPath`, while a separate path renders the globe’s outline. The visualization demonstrates basic choropleth-style mapping using D3 v5’s geo modules.

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.
