World Map

World Map

This example renders a world map from TopoJSON data using D3 v5 and React, drawing countries as filled paths on an SVG canvas. The visualization uses `geoEqualEarth` for the projection, `geoPath` to generate paths, and `geoGraticule` to display a graticule overlay, with a distinct red sphere background and blue landmasses. Country geometries are loaded from the world-atlas TopoJSON file and converted to GeoJSON via `feature()`. The React component hierarchy separates data loading (`useData`) from the presentational `Marks` component.

World Map

This example renders a world map using SVG, displaying country boundaries as paths. The visualization uses the D3 library's geoEqualEarth projection and geoPath to convert geographic data into SVG paths, with React managing the component state. The map draws a semi-transparent background sphere and country outlines in a teal color scheme. The data comes from the world-atlas TopoJSON file, which is fetched and converted to GeoJSON features using the topojson library.

World Map

This example displays a world map rendered as an SVG using React and D3 v5. It loads geographic data from the world-atlas TopoJSON dataset and converts country boundaries into GeoJSON features with `topojson.feature`. The map is drawn as a collection of black path elements, one per country, using a line generator with natural curve interpolation. The visualization focuses on geopolitical outlines rather than thematic data, presenting a minimal, clean cartographic view.

World maping

This example displays a world map rendered as an SVG using React and D3. It shows country boundaries via a spherical equal-earth projection, with land areas filled in teal and the surrounding sphere in light gray. The visualization loads GeoJSON data from the World Atlas TopoJSON file, converts it using topojson’s `feature` method, and draws the paths with `d3.geoPath`. The map is static, with no interaction or animation.

World Map

This example displays a world map rendered as SVG paths using D3.js. It loads geographic data from the world-atlas TopoJSON file and converts it to GeoJSON features via the `topojson.feature` API. The map uses a `d3.geoMercator` projection and `d3.geoPath` to generate the path data for each country. The code demonstrates basic data binding with `selectAll`, `data`, and `enter` to append country shapes to the SVG canvas.

World Map

This example displays a world map constructed from country boundary data. The visualization renders the geographic outlines as a series of black paths, with each path representing a distinct country. The React application loads the world-atlas dataset from the unpkg CDN and processes it using topojson’s feature function. The map is rendered as a static SVG using the d3.line function with natural curve interpolation applied to the coordinate data. No interactivity or additional styling is applied beyond the base strokes.

World Map

This example shows a world map rendered as an SVG using React and D3 v5. It displays the boundaries of countries from the World Atlas TopoJSON dataset, projected with `d3.geoPath`. The visualization uses `d3.json` to load the data and `topojson.feature` to convert it into GeoJSON for rendering. The map is simple and static, focusing on the geographic outlines without additional data encodings or interactions.

World Map

This example visualizes countries from the World Atlas dataset using a frame-like small multiple of a world map, with map boundaries from `topojson`'s `feature` API. The code loads geospatial data via `d3.json` and renders SVG paths with `d3.geoPath`, while React manages the application state. The map is drawn with the `d3.geoPath` projection, and although a line chart path is defined using `d3.line` and `curveNatural`, that mark is not used for the map; instead, only the country features are displayed. The map uses a simple SVG layout with no interactive tooltips.
