This example renders a world map using D3.js and TopoJSON, displaying country boundaries as SVG paths filled with steel blue. The map uses a Mercator projection via `d3.geoMercator` and `d3.geoPath` to convert geographic coordinates into screen paths. It loads world-atlas data from unpkg, extracting country features with `topojson.feature`. The React framework is not actively used in the visible code; instead, the script directly appends paths to an SVG element.

Let's make a map with D3.js!

This example displays a world map rendered with SVG paths, using D3.js v5 and TopoJSON. It loads geographic country boundaries from the world-atlas dataset and projects them with a Mercator projection. The code uses `d3.geoPath` and `d3.geoMercator` to generate the map, while `topojson.feature` converts the TopoJSON data into GeoJSON features. Countries appear filled in steel blue with black, semi-transparent borders, demonstrating a minimal choropleth-style base map.

Let's make a map with D3.js!

This example demonstrates how to create a world map using D3.js and TopoJSON. It renders country boundaries as green SVG paths with thin black strokes on a dark blue background, using a Mercator projection. The visualization loads geographic data from the world-atlas TopoJSON file and converts it to GeoJSON features with the `feature` function. The code uses `d3.geoMercator` and `d3.geoPath` to project the map coordinates and generate the path data.

Let's make a map with D3.js!

This example renders a world map using D3.js and TopoJSON. It loads the world-atlas dataset and converts its TopoJSON topology into GeoJSON features, then draws each country as an SVG path. The map uses the Mercator projection via `d3.geoMercator` and `d3.geoPath` to generate the path data. Country polygons are filled with steelblue and outlined with black strokes, displaying a basic choropleth-style world map without additional data encoding.

Let's make a MAP with D3.js!

This example displays a world map rendered as an SVG, with countries filled in light green and the ocean depicted as a sky-blue sphere. It uses D3 v5 and TopoJSON to load world-atlas data at 110m resolution, then applies the `d3.geoNaturalEarth1` projection and `d3.geoPath` to generate country boundaries. The map also draws a background sphere path, and country strokes are semi-transparent black. The code relies on `topojson.feature` to convert TopoJSON topology into GeoJSON features 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.

Let's make a map with D3.js!

This example renders a world map using D3.js and TopoJSON. It loads country boundaries from the world-atlas dataset and projects them with `d3.geoMercator`. The map is drawn as SVG paths using `d3.geoPath`, with countries filled in green and outlined in black. The code imports specific functions like `select`, `json`, and `feature` from D3 v5 and TopoJSON, and applies a dark blue background via CSS.

Let's make a map with D3.js!

This example renders a world map using D3.js and topojson, displaying country boundaries as light green shapes on a blue sphere. The visualization loads geographic data from the world-atlas TopoJSON file and converts it to GeoJSON features using the topojson `feature` function. D3’s `geoNaturalEarth1` projection and `geoPath` generator draw each country as an SVG path, with a separate path for the global sphere. The code uses the v5 API with imported functions from the d3 module, and styling applies stroke opacity to delineate borders.

Let's make a map with D3.js!

This example shows a world map rendered as SVG paths, with country boundaries drawn from TopoJSON data. The visualization uses D3 v5’s `geoMercator` projection and `geoPath` to convert geographic coordinates into screen paths, while the `topojson.feature` API extracts country geometries from the world-atlas dataset. All countries are appended as individual `path` elements to a 960×500 SVG canvas. The code loads data asynchronously via `d3.json` and relies on the bundled `index.js` to handle the data-binding and path generation.
