This example displays a natural Earth projection world map with graticule lines, country borders, and interior boundaries. City populations are plotted as semitransparent circles with radii scaled by the square root of population using `d3.scaleSqrt`. The visualization uses React hooks to load world atlas TopoJSON data and a CSV of global cities, converting them into GeoJSON features via `topojson.feature` and `topojson.mesh`. D3’s `geoNaturalEarth1` projection and `geoPath` render the SVG shapes.

World Map

This example displays a world map using the Natural Earth projection, rendering landmasses in teal against a light gray sphere with graticule lines. The visualization is built with React and D3 v5, using `d3.geoPath` and `geoNaturalEarth1` to project geographic features, while `topojson` converts the World Atlas dataset into GeoJSON. Country borders appear as thin interior lines, and the map loads asynchronously from a remote TopoJSON source.

Worldmap with cities

This example displays a world map using a Natural Earth projection, with the landmasses rendered as gray polygons and graticules overlaid. City locations are plotted as semi-transparent circles, with their radius scaled by the square root of each city's population. Built with React, the visualization uses D3.js modules `geoNaturalEarth1`, `geoPath`, and `geoGraticule` for the map projections and graticule, while `scaleSqrt` maps population values to circle sizes. City data is loaded from a CSV file, and world atlas geometries are fetched as TopoJSON, which is processed through `topojson` functions.

World Map

This example renders a world map using a natural Earth projection, displaying countries as filled polygons, along with graticules, interior borders, and a sphere outline. It loads geographic data from the world-atlas TopoJSON file and converts it to GeoJSON using the `feature` and `mesh` functions from topojson. The map is drawn with `d3.geoPath` and `d3.geoNaturalEarth1`, while React manages the component structure and SVG rendering. Styling is applied through CSS classes, including a teal fill for landmasses and gray graticules.

World Map

This example shows a world map rendered with a Natural Earth projection, displaying landmasses in teal with graticule lines and country borders overlaid. The map is drawn as SVG paths using `d3.geoNaturalEarth1` and `d3.geoPath`, with geographic data loaded from the world-atlas TopoJSON dataset via `d3.json` and processed through `topojson.feature` and `topojson.mesh`. A React component orchestrates the visualization, applying CSS styling for the sphere, land, and boundary strokes.

World map

This world map visualizes global city populations, with semi-transparent circles sized by population using a square-root scale. A Natural Earth projection draws the landmasses, graticule, and country borders via D3's `geoNaturalEarth1` and `geoPath`, while city coordinates are projected and rendered as SVG circles. The map loads geographic data from World Atlas TopoJSON and population data from a CSV, using `topojson.feature` and `topojson.mesh` to construct the land and interior boundaries.

World Map

This example displays a world map using the Natural Earth projection via D3.js (v5) and React. The visualization renders landmasses, a sphere outline, graticule lines, and interior boundaries as SVG paths, with D3’s `geoNaturalEarth1` projection and `geoPath` generating the geometry. The map is styled with a purple land fill and teal graticule/interior strokes, while the underlying data comes from the `world-atlas` package’s countries-50m GeoJSON topology, processed using `topojson`’s `feature` and `mesh` functions.

World Map

This example visualizes a world map using a natural Earth projection. It displays continents in teal, graticules as light gray lines, and a sphere background, with interior country boundaries emphasized in a darker stroke. The visualization loads GeoJSON world-atlas data and uses React for rendering with D3 v5 APIs such as `geoNaturalEarth1`, `geoPath`, and `geoGraticule`. TopoJSON processes the source data to extract land and interior meshes, all output as SVG paths.

World map

This example displays a world map using the Natural Earth projection, with landmasses filled in blue and country borders drawn as interior lines. A gray graticule grid overlays the sphere, and the entire map is rendered as SVG. The visualization uses React to manage the component structure, D3’s `geoNaturalEarth1`, `geoPath`, and `geoGraticule` to compute projections and paths, and TopoJSON to convert country and land topology from the world-atlas dataset into GeoJSON features.
