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.

This example shows an interactive world map rendered with D3.js, displaying country boundaries colored light green that turn red on hover. The visualization uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to draw geographic features, with zoom support through `d3.zoom`. It loads world-atlas TopoJSON data and a companion TSV file to map country names, appending tooltips with each country’s name. The map is drawn as SVG paths, including a dark blue sphere background.

This example visualizes world countries on a Natural Earth projection, with landmasses rendered in light green against a blue spherical backdrop. The map is drawn as SVG paths using D3.js v5, combining the `geoNaturalEarth1` projection, `geoPath` for geometry generation, and the topojson library’s `feature` function to convert TopoJSON country boundaries. Geographic data is loaded remotely from the world-atlas package, and styling is applied via CSS classes for the sphere and country outlines.

Let's Make a Map with D3.js!

This example shows a world map rendered as an SVG, with countries filled in green and oceans in blue using a Natural Earth projection. The visualization uses `d3.geoNaturalEarth1` to define the projection and `d3.geoPath` to generate the geographic paths. Country outlines are drawn from TopoJSON data loaded from the world-atlas package, converted to GeoJSON via `feature`. A background sphere path is also added to represent the globe. The code relies on D3 v6 and TopoJSON v3 for mapping and data processing.

Let's make a map with D3.js!

This example renders a natural Earth projection map of the world using D3.js and TopoJSON. It draws a blue sphere as the globe background, then loads country boundaries from the world-atlas dataset and fills them with light green polygons, bordered by subtle black strokes. The visualization uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` to generate SVG paths, and `topojson.feature` to extract country geometries from the TopoJSON file.

This example visualizes world countries on a natural Earth projection, filling landmasses in green against a blue ocean sphere. The code loads geographic data from the world-atlas TopoJSON file, converts it to GeoJSON features using topojson’s `feature` function, and renders each country as a SVG path via `d3.geoPath` with `d3.geoNaturalEarth1`. Styling is applied through CSS classes for the sphere and country fills, with the map auto-sized into a 960×500 viewport.

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 shows an interactive world map built with D3.js, displaying country boundaries as SVG paths colored light green, with a blue sphere background. The map supports zooming and panning through a d3.zoom behavior, and hovering over a country turns it red. It uses d3.geoNaturalEarth1 for projection and d3.geoPath for generating paths from TopoJSON data loaded from the world-atlas package, with country names joined from a TSV file and displayed as tooltips via SVG `<title>` elements.
