This example builds a choropleth-style world map using D3.js v5, displaying country boundaries from the world-atlas TopoJSON dataset. The visualization renders the map as SVG paths, with countries filled in light green and a blue sphere for the background. It uses `d3.geoPath` with a `geoNaturalEarth1` projection to project the geographical data, while `topojson.feature` extracts the country geometries. Population data from a CSV file is loaded, though the code only logs country data to the console rather than encoding values visually, and includes a hover effect that turns countries red.

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 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 with countries filled in light green against a blue sphere, rendered as SVG using D3.js v5 and TopoJSON. It uses `d3.geoNaturalEarth1` for projection and `d3.geoPath` to draw country boundaries from the world-atlas dataset. The sphere is drawn as a single path, and country features are generated with TopoJSON’s `feature` method before being appended to the SVG.

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.

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

This example displays world countries as light-green filled polygons on a blue sphere, using a natural Earth projection. It loads country boundaries from the World Atlas TopoJSON dataset and renders them as SVG paths via `d3.geoPath` and `d3.geoNaturalEarth1`. The visualization includes a background sphere path and applies thin black strokes with low opacity to country borders. The code relies on `d3.json` for data fetching and `topojson.feature` to convert TopoJSON to GeoJSON features.

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

This visualization employs D3.js v5 and TopoJSON to render a world map on an SVG canvas. The map uses the Natural Earth dataset loaded from the `world-atlas` package, with country boundaries drawn as SVG paths using the `geoNaturalEarth1` projection and `geoPath` from D3. Countries are filled in light green with black outlines, while the surrounding sphere is filled blue. The code demonstrates DOM manipulation by selecting the SVG element, appending a sphere path, and then adding country paths after asynchronously fetching the geographic data.

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

This map visualization displays world countries colored in light green on a blue sphere, with hover effects turning countries red. It uses D3 v5 and TopoJSON to load and render world geography from the world-atlas dataset. The code combines `d3.geoNaturalEarth1` for projection, `d3.geoPath` for drawing country boundaries, and `d3.zoom` for interactive panning and zooming. Country names are joined from a TSV file and shown as SVG `<title>` tooltips.

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

This fork of the “Let’s make a map with D3.js!” example renders a world map using an SVG canvas with a natural Earth projection. It uses `d3.geoPath` and `d3.geoNaturalEarth1` to project and draw country boundaries from TopoJSON data loaded via `topojson.feature`. The map displays a blue sphere outline and light green countries with thin black strokes, based on the world-atlas 110m dataset. The code loads D3 v5 and TopoJSON v3 from unpkg, with styling applied via an external CSS file.
