Let's make a map with D3.js

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 displays a world map with countries rendered as light green SVG paths on a blue sphere, using a natural Earth projection. The code loads geographic data from the world-atlas TopoJSON dataset and converts it to GeoJSON with topojson’s `feature` method. It builds the map with d3’s `geoPath` and `geoNaturalEarth1` projection, appending country paths and a sphere outline to the SVG canvas.

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 shows a world map using a natural Earth projection, with countries filled in light green and oceans in blue, all rendered as SVG paths. It loads geographic data from the World Atlas TopoJSON dataset via `json()`, then converts the TopoJSON features into GeoJSON using the TopoJSON `feature()` function. The map is drawn with D3’s `geoPath` and `geoNaturalEarth1` projection, and styled with CSS classes for the sphere and countries.

Let's make a map with D3.js!

This example displays a world map in D3.js using the Natural Earth projection (geoNaturalEarth1) and draws country boundaries as SVG paths. It begins by rendering a blue sphere backdrop, then loads geographical data from the world-atlas package via a JSON request. The topojson library’s feature function extracts country geometries, which are then projected and drawn as light green filled paths with subtle black strokes using d3.geoPath. The map is rendered entirely as vector SVG elements, demonstrating a basic choropleth setup with static styling.

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 renders a world map in a natural Earth projection using the d3.js library. It displays continents in green against a blue spherical backdrop, with country boundaries outlined in black. The visualization fetches GeoJSON data from the world-atlas package, converts it using the topojson `feature` function, and projects it onto an SVG canvas with `d3.geoPath` and `d3.geoNaturalEarth1`. The map is styled via CSS classes for the sphere and individual countries.
