World and Country Map

World Map

This example displays a world map by rendering country boundary shapes from a GeoJSON file using an equal-earth projection. It loads the geographic data with d3.json and draws each country as an SVG path via d3.geoPath. The map is appended to the page inside a fixed-size SVG container, demonstrating a minimal setup for showing vector-based geographic shapes with D3 version 6.

World Map Visualization

This example renders a world map using D3.js and SVG, showing country boundaries as light blue shapes with white strokes. It loads GeoJSON world map data from a remote repository and applies a Mercator projection to convert geographic coordinates into screen positions, with the map centered on the canvas. The visualization demonstrates key D3 features such as `d3.geoMercator`, `d3.geoPath`, and loading external data via `d3.json`, alongside ES6 module imports from a local file. The map is drawn by binding the GeoJSON features to SVG `path` elements, with styling applied via inline attributes.

World Map Visualization

A world map visualization colors each country according to a numeric value from an external CSV dataset. The example uses D3 v6 with a Mercator projection via `d3.geoMercator` and `d3.geoPath` to render GeoJSON country boundaries as SVG paths. Country fill colors are determined by a sequential blue color scale, while missing data appears gray. The code demonstrates loading remote TopoJSON and CSV files with `d3.json` and `d3.csv`, and includes an ES6 module import for a simple message.

Country Map with d3.js

This example displays a world map using D3.js, coloring individual countries based on sample population data. It shows a Mercator projection of the globe, with the United States and China shaded according to the provided values. The visualization constructs the map by appending SVG paths from GeoJSON data to the chart. It relies on D3 APIs including `d3.geoMercator`, `d3.geoPath`, `d3.json`, `d3.scaleLinear`, and `d3.extent` to handle the projection, rendering, and color encoding, with a domain from data values mapped to a light-to-dark color range.

World Map with d3.js

This example renders a world map as an SVG using D3.js version 7. It applies a Mercator projection via `d3.geoMercator` and draws country boundaries with `d3.geoPath`, styling each path with a gray fill and dark stroke. The map loads GeoJSON country data from a remote GitHub repository using `d3.json`, and the visualization is contained within an HTML page that imports D3 from a CDN. The code demonstrates basic map projection and data binding in a simple, static geographic visualization.

World Map

This example displays a static world map rendered in SVG, with countries filled in green against a light blue ocean background. It uses D3 v4 with a Mercator projection via `d3.geoPath` and `d3.geoMercator` to trace country boundaries. Geographic data comes from the world-atlas TopoJSON file, processed with `topojson.feature`. The map is centered within an SVG canvas using explicit margins, and the overall color scheme includes a light beige page background.

World Map

This example renders a world map as a static SVG graphic. It displays countries in orange against a blue sphere, with a red hover highlight effect. The visualization uses D3.js functions `select`, `json`, `geoPath`, and `geoEquirectangular` for the equirectangular projection. It loads GeoJSON country boundaries from the `world-atlas` package via `json()`, converting them with the TopoJSON `feature` API before drawing with `geoPath`. The stylesheet defines the sphere and country fills.
