This example displays a world map using a Mercator projection, rendering country boundaries as SVG paths from TopoJSON data. The visualization fetches the world-atlas dataset and uses `d3.geoPath` with a `geoMercator` projection to convert geographic coordinates into screen paths. Each country is appended to the SVG as a separate path element. The code relies on D3 v5 and the topojson library to parse and extract country features from the TopoJSON format.

World Map with the world Topojson data

This example displays a world map using the Mercator projection, with each country rendered as a filled SVG path along a light green background and dark green borders. The map is built with the d3.geo.path API, which generates path data from the TopoJSON geometry of the world-atlas dataset. The code loads geographic data from a JSON file and uses topojson.object to extract country boundaries before injecting them into SVG path elements for visualization.

World Map using Mercator Projection

This example displays a world map using the Mercator projection, rendered as SVG paths with countries filled in white on a blue ocean background. It loads GeoJSON country boundaries from a gist and uses `d3.geoMercator` for projection, `d3.geoPath` to generate the paths, and `topojson.feature` to convert TopoJSON data. A sphere outline is drawn first, and country paths are appended dynamically from the fetched dataset.

let's make a world map

This interactive map renders world countries as SVG paths using a Mercator projection. The visualization loads country boundaries from a world-atlas GeoJSON/TopoJSON dataset and draws them server-side with D3’s `geoPath` and `geoMercator`. The code employs `topojson.feature` to convert topological data into geometric features, then appends each path to the SVG canvas.

World Map with Topojson data

This example displays a world map using TopoJSON data, rendering countries as blue-filled paths with pink strokes against a white spherical backdrop. It uses D3 v5’s `geoMercator` projection and `geoPath` to convert geographic coordinates into SVG paths, while the TopoJSON library’s `feature` method extracts country geometries from a remote JSON file. The visualization loads data asynchronously via `json` and appends each country path to the SVG canvas, demonstrating a straightforward choropleth-free baseline of global boundaries.

making a map

This example renders a world map using the Mercator projection, displaying country boundaries as SVG paths. The code loads geographic data from the World Atlas TopoJSON file, converts it to GeoJSON using `topojson.feature`, and draws the countries with `d3.geoPath`. The map is created with d3.v7, using a static SVG canvas sized to 960 by 500 pixels. The visualization demonstrates a straightforward approach to converting TopoJSON into a projected map with minimal styling.

Let's make a map

This example displays a world map rendered as SVG paths, showing country boundaries in a simple Mercator projection. The visualization loads geographic data from a world-atlas TopoJSON file and converts it to GeoJSON using the topojson `feature` method. It uses d3.json to fetch the data, d3.geoMercator for the projection, and d3.geoPath to generate the path data, appending each country as a `<path>` element to the SVG.

Let's make a map

This example shows a world map rendered as SVG paths, with each country outlined using a Mercator projection. The code loads a GeoJSON-like dataset from the world-atlas package and uses the `topojson` library's `feature` function to extract country features. It then applies `d3.geoMercator` for the projection and `d3.geoPath` to generate the path data for each country, appending them to the SVG canvas.

World Map with Topojson data

This example displays a world map rendered as SVG paths, with countries in grey and yellow strokes against a red spherical backdrop. It uses the Mercator projection and D3’s `geoPath` to convert geographic coordinates into screen paths, while TopoJSON’s `feature` extracts country boundaries from a remote world.json file. The sphere and countries are appended directly to the SVG via D3’s `select` and data joins, with styling handled through CSS classes.
