This example renders a world map using D3.js and TopoJSON. It draws country boundaries as SVG paths projected with a Mercator projection using `d3.geoMercator` and `d3.geoPath`. The map loads geographic data from the world-atlas countries-110m JSON file, converts TopoJSON to GeoJSON with the `feature` function, and appends each country path to the SVG. The visualization demonstrates a basic choropleth-free mapping workflow with styled countries and a blue sphere background.

Let's make a map with D3.js!

This example displays a world map using a blue sphere background and light green country polygons, with a thin black stroke outlining each nation. It loads geographic boundaries from the World Atlas TopoJSON dataset and renders them as SVG paths via `d3.geoPath` with the `d3.geoAlbersUsa` projection. The code uses `topojson.feature` to convert TopoJSON geometry into GeoJSON features. A video link in the README suggests the visualization accompanies a tutorial on creating maps with D3.

Let's make a map with D3.js!

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.

Let's make a map with D3.js

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!

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.

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 dark blue sphere background. It loads geographic data from the world-atlas TopoJSON dataset and converts it to GeoJSON using the `feature` function from topojson. The map projects coordinates with `geoNaturalEarth1` and draws each country boundary via `d3.geoPath`, while a separate path renders the globe’s outline. The visualization demonstrates basic choropleth-style mapping using D3 v5’s geo modules.

Let's make a map with D3.js!

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.

Let's make a map with D3.js!

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.
