Let's make a map with D3.js!

This example displays a world map using an orthographic projection, rendering countries as light-green SVG paths against a dark blue background. The map is built entirely with D3.js v5 and TopoJSON, loading geographic data from the world-atlas dataset. The code uses `d3.geoOrthographic` and `d3.geoPath` to project and trace country boundaries, while `topojson.feature` extracts the geometries for rendering.

This example displays a world map rendered as light green countries against a dark blue background using an SVG projection. It loads geographic data from the `world-map` package via TopoJSON, then uses D3’s `geoEquirectangular` projection and `geoPath` to draw each country’s borders. The code relies on D3 v5 selections and the TopoJSON `feature` method to convert topology into GeoJSON. Paths are styled with a faint black stroke and two-pixel width.

This example shows a world map rendered as SVG paths, with countries filled in light green against a dark blue spherical backdrop. Using D3 v5, it loads world-110m TopoJSON data via `d3.json`, converts the TopoJSON features with `topojson.feature`, and projects them using `d3.geoNaturalEarth1` and `d3.geoPath`. A separate path for the sphere applies the same projection to outline the globe, while country borders are drawn with a subtle black stroke.

This example uses D3.js to render a world map with an orthographic projection on an SVG. It loads country boundary data from the world-atlas TopoJSON file, converts it to GeoJSON with the `feature` function, and draws the paths using `d3.geoPath` and `geoOrthographic`. The map shows all countries filled in green with black strokes against a sky blue background.

This example renders a world map as a set of light-green SVG paths against a dark blue background. It uses a stereographic projection and d3.geoPath to draw country boundaries from TopoJSON data, sourced from the world-map package. The map is static, with each country outlined by a semi-transparent black stroke, and the code demonstrates a minimal setup for geographic visualization with D3 v5 and TopoJSON.

This example demonstrates how to create a world map with D3.js, rendering countries as light-green SVG paths on a dark blue background. It uses the `geoMercator` projection and `geoPath` to convert geographic coordinates into SVG path data, while TopoJSON’s `feature` method extracts country boundaries from a world-110m dataset loaded from unpkg. The visualization focuses on a clean, minimal map with thin black strokes separating countries, making it a straightforward introduction to geo-spatial data visualization.

Let's make a map with D3.js!

This example uses D3.js and TopoJSON to generate an orthographic projection map of the world. It loads world country boundaries from a JSON file hosted on unpkg, converts the TopoJSON data into geographic features, and renders each country as a green SVG path with a subtle black stroke. The visualization employs `d3.geoOrthographic` and `d3.geoPath` to create the projection, with the dark blue background and minimal styling coming from the linked CSS.

This example shows a simple orthographic world map rendered as an SVG, with countries filled in light green and a blue sphere representing the globe. It uses D3 v5’s `geoOrthographic` projection and `geoPath` to draw country boundaries from TopoJSON data loaded from the world-atlas dataset. The code appends a sphere path, then fetches the TopoJSON file, converts it to GeoJSON with the `feature` function from the topojson library, and binds the resulting country features to SVG paths.
