Let's make a map with D3.js!

This example demonstrates how to create an interactive world map using D3.js v5 with TopoJSON data from the world-atlas package. The map renders countries as SVG paths using the `d3.geoNaturalEarth1` projection and `d3.geoPath` generator, with a blue sphere background. Country shapes are filled green and turn red on hover, while each path includes a title element displaying "hello". The code loads geographic data asynchronously via `d3.json` and converts TopoJSON features using the `feature` function from the topojson library.

This example renders a world map of countries using D3.js and TopoJSON. It loads geographic data from the world-atlas dataset and displays country boundaries as SVG paths. The visualization uses `d3.geoMercator` for the projection and `d3.geoPath` to generate the path data from the TopoJSON features. Each country is appended as a `path` element to an SVG canvas sized 960 by 500 pixels.

This example renders a world map using D3.js and TopoJSON. It loads country boundaries from the world-atlas dataset and projects them with `d3.geoMercator`. The map is drawn as SVG paths using `d3.geoPath`, with countries filled in green and outlined in black. The code imports specific functions like `select`, `json`, and `feature` from D3 v5 and TopoJSON, and applies a dark blue background via CSS.

This example shows a geographic world map rendered as an SVG using D3.js and TopoJSON. It displays country boundaries and a blue sphere outline, with countries filled in light green and subtle black strokes. The code loads world-atlas data via D3’s `json` method and converts TopoJSON features using `topojson.feature`. It applies a natural Earth projection with `d3.geoNaturalEarth1` and generates paths via `d3.geoPath`. The visualization relies on D3 v5 and TopoJSON v3 scripts.

This example creates a world map rendered as SVG using D3 v5 and TopoJSON. It loads world country boundaries from the World Atlas TopoJSON dataset, projects them with the `geoNaturalEarth1` projection, and draws each country as a filled path using `d3.geoPath`. A blue sphere background is added first, with countries shown in light green and outlined with subtle black strokes. The map displays the entire globe with country shapes accurately projected.

This example renders a world map using D3.js and TopoJSON, applying the natural Earth projection via `d3.geoNaturalEarth1` and drawing country boundaries with `d3.geoPath`. The SVG shows a blue sphere outline and light green countries with subtle black strokes. It loads country geometries from the world-atlas 110m TopoJSON dataset and converts them to GeoJSON using TopoJSON’s `feature` function. The code appends paths for the sphere and each country, demonstrating a straightforward choropleth-free geographic visualization.

Let's make a map with D3.js!

A world map is rendered using D3.js, with countries filled in light green against a blue sphere. The example demonstrates a basic geographic visualization workflow, loading TopoJSON data from the World Atlas and converting it to GeoJSON features. The code uses `d3.json`, `d3.geoPath`, `d3.geoNaturalEarth1`, and the TopoJSON `feature` method to project and draw the paths as SVG elements. The map is static, showing only country boundaries and the projected Earth sphere.

This example displays a world map rendered as blue SVG paths with white borders, highlighting each country in red on hover. It demonstrates a basic geographic visualization workflow using D3.js, loading country boundaries from the world-atlas TopoJSON dataset and converting them with `d3.geoMercator` projection and `d3.geoPath`. The code uses `topojson.feature` to extract GeoJSON from the TopoJSON file and appends the resulting paths to an SVG canvas, with hover styling handled by CSS.
