This example shows a natural Earth projection of the world, rendered as a blue sphere with no country boundaries loaded yet. The visualization uses D3 v5’s `geoNaturalEarth1` projection and `geoPath` to draw the sphere outline, while `topojson.feature` is called on an external GeoJSON file fetched via `d3.json`. The SVG canvas is 960 by 500 pixels, with the sphere filled in blue and CSS classes prepared for future country styling. The code’s console logs the fetched data but does not yet display it on the map.

Let's make a map with D3.js!

This example displays a natural Earth projection map of the world, rendered as a single blue sphere with country boundaries drawn in light green. The visualization first appends a sphere path using `d3.geoPath` with a `d3.geoNaturalEarth1` projection, then loads GeoJSON data from a remote URL via `d3.json` and converts it to GeoJSON features using `topojson.feature`. The map is rendered as SVG within an HTML page, with styling for the sphere and country fills defined in an external stylesheet.

Let's make a map with D3.js!

This example shows a single blue sphere representing the Earth, rendered in an SVG canvas, with a natural Earth projection. The map is drawn using D3.js version 5, specifically the `geoNaturalEarth1` projection and `geoPath` generator, while the sphere outline is created with a `pathGenerator` on a `{type: 'Sphere'}` object. The code loads external TopoJSON data via `topojson.feature`, though the current implementation only logs the fetched data to the console and does not yet display country boundaries. The visualization uses static SVG paths with CSS classes for styling.

Let's make a map with D3.js!

This example demonstrates how to create a world map using D3.js, displaying a blue sphere with a natural Earth projection and a green landmass rendered as SVG paths. The visualization uses `d3.geoPath` with a `d3.geoNaturalEarth1` projection to draw the sphere outline, while TopoJSON data is loaded from an external URL using `d3.json` and processed with TopoJSON’s `feature` method. The code imports specific D3 modules like `select`, `json`, `geoPath`, and `geoNaturalEarth1`, and styles the sphere and country paths via CSS classes.

Let's make a map with D3.js!

This example shows a world map rendered as an SVG, featuring a blue sphere background and light green country outlines. It demonstrates a basic D3.js geographic visualization using `d3.geoNaturalEarth1` for the projection and `d3.geoPath` to generate path data for the sphere. The map loads TopoJSON data from a GitHub-hosted `.json` file via `d3.json` and the `topojson` library's `feature` module, though the country data is only logged to the console rather than drawn. The code imports specific D3 functions (`select`, `json`, `geoPath`, `geoNaturalEarth1`) and relies on v5 syntax, with CSS applying fill and stroke styling to the sphere and country paths.

Let's make a map with D3.js!

This example visualizes a world map using D3.js with a blue sphere background and green country shapes. It loads geographic data from an external JSON file and renders it as SVG paths using the `d3.geoPath` and `d3.geoNaturalEarth1` projection. The code employs TopoJSON’s `feature` method (though not yet called in the visible portion) and logs the fetched data to the console. The styles define the sphere’s fill color and country borders with a low stroke opacity.

Let's make a map with D3.js!

This example demonstrates how to create a world map using D3.js version 5 and the TopoJSON library. It displays a blue sphere representing the globe and uses the Natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to render geographic boundaries. The map is rendered as an SVG element, with country borders styled in light green and black strokes. The code loads geographic data from a remote `borders-parsed.jsonp` file, though the actual data fetching and subsequent rendering of individual countries is not fully implemented in the visible code.

Let's make a map with D3.js!

This example demonstrates how to create a world map using D3.js, rendering countries with a natural Earth projection. It displays a blue sphere background and green country shapes with subtle black borders. The code uses D3's `geoNaturalEarth1` projection and `geoPath` to generate SVG paths, while the TopoJSON library's `feature` function extracts country boundaries from a world-atlas dataset. The visualization loads geospatial data from a remote JSON file and renders the map entirely as scalable vector graphics.
