This example displays a stereographic projection map of the 28 European Union countries as of 2016, with each nation drawn as a filled SVG path. It uses D3 v3 and TopoJSON to load and render geographic features from an external `output_small.json` file, while `d3.geo.stereographic()` defines the projection and `d3.geo.path()` generates the path data. The visualization highlights individual countries on mouseover by updating a text element with the country’s name from the `GEN` property. The map is static apart from this hover interaction, with no animation or color scale applied beyond the default black fills.

Template D3

This example visualizes the output of 28 EU countries from 2016 using a stereographic map projection. It loads TopoJSON data containing country boundaries, renders them as SVG paths, and colors each country with a sequential scale (commented out in the code). The map includes hover interactions that display the country name in a heading, and the land and boundary styling uses grey and blue fills with a distinct path stroke. The visualization leverages D3 v3 and TopoJSON for geographic data rendering, with animations omitted in this static version but structured to support future transitions.

Europe Map

This example visualizes the countries of Europe as a static SVG map using a Mercator projection centered on the continent. The code loads GeoJSON feature data via `d3.json` and renders each region as a `path` element using `d3.geoPath` with the projection. React and D3 v5 are used together to manage the document, while TopoJSON is loaded but not directly applied in the visible logic. Country boundaries appear as grey strokes with white fills, set through SVG attributes.

Map with D3.js

This map visualization displays world countries on a natural Earth projection using D3.js and TopoJSON data from the world-atlas dataset. It renders an SVG sphere background and country paths filled with teal, which turn red on hover through CSS. The code employs D3 v6 features like `geoNaturalEarth1` and `geoPath` to project geographic coordinates, while `topojson.feature` extracts country boundaries from the loaded TopoJSON file. A tooltip showing each country’s name appears via appended `title` elements.

Let's make a map with D3.js!

This example displays a world map rendered as SVG paths, with countries filled in teal against a blue sphere backdrop using an equal-earth projection. It loads geographic data from the world-atlas TopoJSON dataset, converts it to GeoJSON with the `feature` function from Topojson, and projects it through `d3.geoPath` combined with the `geoEqualEarth` projection from d3-geo-projection. The visualization demonstrates a minimal, clean map-making workflow using D3 v5.

Let's make a map with D3.js!

This example uses a natural Earth projection to render a world map from TopoJSON data, with countries drawn as filled paths and a dark blue sphere as the base. It builds the visualization by loading the world-atlas dataset from unpkg and using `d3.geoNaturalEarth1` for the projection, `d3.geoPath` to generate SVG paths, and the `topojson.feature` method to convert TopoJSON to GeoJSON. The result is a simple, static SVG map with light green countries and translucent black strokes.

Map.js!

This map visualization displays the world’s countries by using a Mercator projection to render geographic features as filled SVG paths on a light gray sphere background. The code loads country boundaries from the world-atlas TopoJSON dataset and converts them to GeoJSON with `topojson.feature`, then draws each country using `d3.geoPath`. Styling applies a blue fill with dark strokes and a subtle opacity, while the hidden overflow and full-bleed body create an immersive, full-window presentation.

Let's make a map with D3.js!

This example uses D3.js to render an interactive world map from TopoJSON and TSV data loaded from the world-atlas package. Countries are drawn as SVG paths using the d3.geoNaturalEarth1 projection and d3.geoPath, with hover effects changing their fill color. The visualization incorporates d3.zoom to enable pan and zoom transformations on the map group, while a sphere background is rendered from a GeoJSON Sphere object. Country names are joined to features via ISO numeric codes and displayed as SVG title tooltips.

D3.js map

This visualization displays a flat, natural Earth projection map of world countries, rendered as a single SVG with light green landmasses and a light blue ocean sphere. It uses D3.js v7 (with `select`, `json`, `geoPath`, and `geoNaturalEarth1`) and TopoJSON’s `feature` method to load and convert country boundaries from the world-atlas dataset. The code appends paths for the sphere and each country, styling them via CSS, and runs entirely client-side in a bare HTML page.
