Creating a map with data in d3

Fork of Fork of Let's make a map with D3.js!

This example shows a world map rendered as a bright pink sphere with yellow country shapes outlined in green. It uses D3 v5 and TopoJSON to load geographic data from a GitHub-hosted JSON file. The map is drawn in SVG using `d3.geoPath` with the `geoNaturalEarth1` projection, and country boundaries are generated via `feature` from the topojson library. The sphere and countries are styled with CSS classes.

This example displays a world map as an SVG graphic, with each country rendered as a green path with black outlines. Hovering over a country changes its fill color to orange, providing basic user feedback. The visualization uses D3 v5 functions such as `select`, `json`, `geoPath`, and `geoEquirectangular` for the projection, while TopoJSON’s `feature` method converts the loaded world-atlas countries-110m.json data into GeoJSON features for rendering.

This example presents a static world map rendered as SVG, showing countries as pink regions on a sky-blue spherical backdrop. The map is built using D3.js version 5 and the topojson library, which decodes GeoJSON-like data from the `world-atlas` package. The `d3.geoPath` and `d3.geoNaturalEarth1` APIs handle the projection and path generation. The code first draws a full sphere, then loads country boundaries from a remote JSON file and appends them as separate paths. The styling uses a faint blue stroke for country borders.

This example renders a static world map using D3.js and TopoJSON. It loads country boundaries from a world-atlas TopoJSON file, converts them to GeoJSON with `feature()`, and draws them as SVG paths with a `geoEquirectangular` projection and `geoPath`. A dark blue sphere background and yellow countries with white strokes are styled via CSS, with a hover effect that highlights each country in bright yellow.

This example displays a world map rendered as blue SVG paths for the oceans and green-filled country polygons with black strokes, based on geographic data from the world-atlas TopoJSON dataset. The code imports `geoEquirectangular` and `geoPath` from d3 to project coordinates, and uses `feature` from topojson to convert TopoJSON topology into GeoJSON features. A single empty path is first appended for the sphere outline, then country paths are added dynamically once the JSON data loads asynchronously.

This example renders an interactive world map using D3.js and TopoJSON. It displays countries as white polygons with black outlines on a blue sphere, and highlights individual countries in orange on hover. The visualization uses `d3.geoEquirectangular` for projection and `d3.geoPath` to generate SVG paths. Country geometry is loaded from a world-atlas TopoJSON file hosted on jsDelivr, with features extracted via the `feature` function.
