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 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.

This example demonstrates how to create a simple world map using D3.js, displaying countries as light green polygons against a blue sphere background. The visualization uses the `geoNaturalEarth1` projection and `geoPath` to generate SVG paths from TopoJSON data loaded from the world-atlas dataset. The code relies on D3 v5 and the topojson library, specifically using the `feature` function to convert TopoJSON to GeoJSON. The map is rendered entirely with SVG elements, with the sphere outline drawn first, followed by the country boundaries.

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.

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.

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.
