This example renders a choropleth-style map of Indian districts using D3.js and TopoJSON. The visualization displays administrative boundaries as light green SVG paths with subtle black stroke outlines, projected using the Natural Earth projection via `d3.geoNaturalEarth1` and drawn with `d3.geoPath`. Geographic data is loaded asynchronously from a remote TopoJSON file, with the TopoJSON `feature` API extracting the district geometries. The code uses D3’s `select`, `json`, and `enter` methods to attach the projected paths to an SVG canvas.

Let's make a map with D3.js!

This example renders a world map using D3.js version 5 and TopoJSON, displaying countries as light green paths with subtle black strokes against a blue spherical backdrop. It uses `d3.geoNaturalEarth1` for the projection and `d3.geoPath` to generate SVG paths from geographic features. The map loads country boundaries from the world-atlas TopoJSON dataset (110m resolution) via `d3.json`, then appends each country path to the SVG canvas. The visualization demonstrates a clean, static cartographic rendering suitable for introductory mapping tutorials.

Let's make a map with D3.js!

This example visualizes U.S. county boundaries as a natural Earth projection map, with the sphere background filled in blue and country shapes rendered in light green. It loads GeoJSON data from a freeCodeCamp choropleth dataset and uses `d3.geoPath` with `d3.geoNaturalEarth1` to project and draw the paths. The code selects an SVG element, appends a sphere path, then joins the TopoJSON features to append individual county paths using D3's data join. The map is static, with no interaction or animation beyond the initial rendering.

Let's make a map with D3.js!

This example demonstrates how to create a world map using D3.js and TopoJSON. It displays countries as light green geographic regions against a blue sphere, using the Natural Earth projection via `d3.geoNaturalEarth1` and rendering paths with `d3.geoPath`. The map loads geographic data from the world-atlas TopoJSON file, extracting country features with the `feature` method from topojson. SVG paths are appended for each country, with styling applied through CSS classes for the sphere and country boundaries.

Let's make a map with D3.js!

This example displays a world map using a natural Earth projection, with each country rendered as a light green SVG path. The visualization loads geographic data from the world-atlas TopoJSON file and converts it to GeoJSON using the topojson feature function. D3 v5’s geoNaturalEarth1 projection and geoPath generator handle the map’s shape and layout. The map appears static, with country borders outlined in black and a subtle stroke opacity, though no sphere or ocean background is drawn.

Map with React & D3

This example renders a choropleth map of India using React and D3. It displays state boundaries as SVG paths, filled with a teal color, against the full browser viewport. The map is projected using `d3.geoMercator` and drawn with `d3.geoPath`, while TopoJSON data is fetched from a remote gist and converted to GeoJSON via the `feature` function. React components manage the data loading lifecycle and render the SVG elements, with D3 handling the geographic calculations.

Let's make a map with D3.js!

This map example renders the countries of the world using an SVG canvas and a Natural Earth projection. The visualization draws a blue sphere as a background, then fills each country's geographic boundary in light green with a semi-transparent black outline. The code uses the D3.js libraries `d3.geoPath` and `d3.geoNaturalEarth1` to project and draw the map, while the `topojson` module's `feature` function converts the TopoJSON data from the world-atlas package into plottable country features.

Let's make a map with D3.js!

This example displays a geographic map using D3.js and TopoJSON. It shows country boundaries projected with the Natural Earth projection. The map is rendered as SVG paths generated from a GeoJSON dataset loaded from an external URL. The code uses `d3.geoPath()` to generate the path data and `d3.geoNaturalEarth1()` for the projection, with the TopoJSON library converting the input data into geographic features.
