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.

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 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 displays a world map rendered as SVG paths using D3.js. It loads world-atlas TopoJSON data via `d3.json`, converts it to GeoJSON with `topojson.feature`, and projects it using `d3.geoMercator`. The `d3.geoPath` generator sets the `d` attribute for each country path through a data join, producing a simplified 110m-resolution map.

Let's make a map with D3.js!

This example demonstrates how to create a world map using D3.js. It loads geographic data from the World Atlas TopoJSON file and projects country boundaries with a spherical Mercator projection. The visualization uses `d3.geoPath` and `d3.geoMercator` to convert GeoJSON features into SVG paths, with the TopoJSON library’s `feature` method extracting country polygons. The resulting map renders as simple filled paths on a blank SVG canvas, showing the continents and country outlines.

Let's make a map with D3.js!

This example shows a world map rendered as SVG paths, with countries filled in light green against a blue sphere. It uses D3.js version 5 and TopoJSON to load and convert world-atlas data from unpkg. The map is drawn using `d3.geoPath` with a `d3.geoNaturalEarth1` projection, and country boundaries are derived via `topojson.feature`. A static sphere outline is added first, then country paths are appended to the SVG. The code relies on promises to fetch and process the geographic data asynchronously.

Let's make a map with D3.js!

This example creates a world map rendered as SVG using D3 v5 and TopoJSON. It loads world country boundaries from the World Atlas TopoJSON dataset, projects them with the `geoNaturalEarth1` projection, and draws each country as a filled path using `d3.geoPath`. A blue sphere background is added first, with countries shown in light green and outlined with subtle black strokes. The map displays the entire globe with country shapes accurately projected.

Let's make a map with D3.js!

This example shows a simple world map rendered as an SVG, with countries filled in light green against a blue ocean sphere. The code uses D3 v5’s `geoMercator` projection and `geoPath` to draw geographic features, while TopoJSON’s `feature` method extracts country boundaries from the world-atlas dataset. Country paths are appended dynamically after loading the 110m resolution GeoJSON via a promise, with styling applied through CSS classes.
