This example shows a world map rendered as SVG paths, with countries filled in light green against a blue spherical background. It uses D3 v5’s `geoNaturalEarth1` projection and `geoPath` to generate the map, while TopoJSON’s `feature` extracts country boundaries from the world-atlas dataset (110m resolution). The code appends a sphere path first, then loads the TopoJSON data asynchronously and appends individual country paths, styling them via CSS classes. The result is a static, interactive-free choropleth-style map.

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

This example displays a world map rendered as SVG paths, with countries filled in light green against a blue spherical backdrop. It uses D3.js v5’s `geoPath` and `geoNaturalEarth1` projection to generate geographic outlines from the world-atlas TopoJSON dataset. The code also loads the TopoJSON library to extract country features, then appends each path to the SVG container. The visualization demonstrates a straightforward choropleth-style map without interactivity, emphasizing the projection and vector rendering pipeline.

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

This example displays a world map with countries filled in light green against a blue spherical backdrop, rendered as SVG paths using D3.js v5 and TopoJSON. It uses `d3.geoNaturalEarth1` for the projection, `d3.geoPath` to generate country outlines, and fetches geographic data from the World Atlas TopoJSON source (110m resolution). The code appends a sphere path first, then loads and draws country features, with stroke opacity creating thin borders.

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

This example displays a world map using a natural Earth projection, with countries filled in light green and oceans in blue. It renders geographic boundaries as SVG paths, generated from a world-atlas dataset loaded via D3’s `json` function. The code employs `d3.geoPath` with the `geoNaturalEarth1` projection and uses the `topojson` library’s `feature` method to extract country geometries from the TopoJSON data. A static sphere outline is drawn first, followed by each country path, with stroke opacity creating subtle border definition.

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

This map visualizes the countries of the world on a blue sphere using a natural Earth projection. It renders geographic boundaries with a light green fill, black strokes, and a semi-transparent stroke opacity. The code uses D3 v5’s `geoNaturalEarth1` and `geoPath` to project and draw features, while TopoJSON’s `feature` extracts country polygons from the world-atlas dataset. A static SVG path for the sphere is appended first, followed by dynamically appended country paths.

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

This example renders a world map using a natural Earth projection, displaying country boundaries as colored paths over a blue spherical backdrop. It loads geographic data from the world-atlas TopoJSON dataset and converts it to GeoJSON using the topojson `feature` method. The map is drawn with D3 v5’s `geoPath` and `geoNaturalEarth1` projection, while each country is styled as a light green filled SVG path with a subtle black stroke. The visualization demonstrates a straightforward, static cartographic rendering with minimal interactive or animated elements.

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

This example uses D3 v5 and TopoJSON to render a natural Earth projection world map. It draws a blue sphere outline via a `geoNaturalEarth1` projection and `geoPath`, then loads country boundaries from the world-atlas 110m TopoJSON dataset. Each country is appended as an SVG path with a light green fill and black stroke, while the sphere is colored dark blue. The map is static and demonstrates basic geographic data loading, projection, and SVG rendering.

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

This example visualizes a world map using a natural Earth projection, rendering countries as light green paths with dark strokes on a blue spherical backdrop. It loads geographic data from a world-atlas TopoJSON file via `d3.json`, then applies the `topojson` library’s `feature` function to extract country features. The SVG paths are generated using `d3.geoPath` and the `d3.geoNaturalEarth1` projection, which also draws the sphere outline. The input data source is the unpkg-hosted world-atlas dataset, and the rendering is entirely vector-based, using SVG elements styled by the included CSS.

This example shows a world map with countries rendered in light green against a blue sphere, using a natural Earth projection. It loads geographic data from the world-atlas TopoJSON file, then converts it to GeoJSON features with the topojson `feature` method. D3’s `geoPath` and `geoNaturalEarth1` projection generate the SVG paths for each country, while a separate path outlines the globe. The visualization is a minimal, static map demonstrating basic D3 geospatial rendering.
