A D3.js visualization renders a world map using a natural Earth projection, coloring countries light green against a dark blue ocean sphere. The example demonstrates geographic data mapping by fetching TopoJSON country boundaries from the world-atlas dataset and converting them to GeoJSON with topojson.feature. SVG paths are generated with d3.geoPath and the geoNaturalEarth1 projection, with each country receiving stroke styling to show borders. The code imports select, json, and geoPath from d3.v5, showcasing a minimal, single-file approach to interactive map creation.

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 and oceans shown as a blue sphere. The code loads geographic data from the world-atlas TopoJSON file, converts it to GeoJSON using the topojson `feature` function, and draws it with `d3.geoPath` and `d3.geoNaturalEarth1` from D3 v5. A single SVG element sized 960 by 500 hosts the visualization.

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 visualizes world countries as a natural Earth projection map, with landmasses rendered in light green against a dark blue spherical backdrop. Using D3 v5, it loads TopoJSON data from the world-atlas package and converts it to GeoJSON via topojson.feature, then draws each country with d3.geoPath and a d3.geoNaturalEarth1 projection. The map is rendered as SVG paths onto a fixed 960×500 canvas.

Let's make a map with D3.js!

This example shows an interactive world map where countries appear in light green against a blue ocean sphere, using the Natural Earth projection. The visualization loads geographic data from the world-atlas dataset and renders vector paths with SVG. The code imports D3.js functions including geoNaturalEarth1 for the projection, geoPath for generating path data, and select for DOM manipulation. Country boundaries are drawn from TopoJSON features using the topojson library, while styling comes from the attached CSS file.

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 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 shows a world map rendered as an SVG using D3.js with a natural Earth projection. The map displays country boundaries in light green with subtle black strokes against a blue sphere background. It loads GeoJSON data from the world-atlas TopoJSON dataset and converts it using topojson.feature. The visualization demonstrates D3’s geoPath generator to project geographic coordinates, with selectable projection types commented in the code for experimentation.
