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 with dark strokes. It loads geographic data from a TopoJSON world-atlas file via `d3.json`, then converts it to GeoJSON using `topojson.feature`. The map is drawn with `d3.geoPath` and `d3.geoOrthographic`, projecting the spherical landmasses onto a flat plane. The dark blue background and minimal styling emphasize the Earth’s curved shape, creating a simple globe-like visualization.

Let's make a map with D3.js!

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.

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.

Let's make a map with D3.js!

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 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.

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.

Let's make a map with D3.js!

This example renders a world map of countries using D3.js and TopoJSON. It loads geographic data from the world-atlas dataset and displays country boundaries as SVG paths. The visualization uses `d3.geoMercator` for the projection and `d3.geoPath` to generate the path data from the TopoJSON features. Each country is appended as a `path` element to an SVG canvas sized 960 by 500 pixels.
