This visualization displays cities as semi-transparent circles on a natural Earth projection, with circle size encoding population using a square-root scale. It renders world land masses, graticules, and country interiors via `geoPath` and `geoNaturalEarth1`, while city positions are projected from latitude and longitude coordinates. Data comes from a CSV of world cities loaded with `d3.csv`, and the world atlas TopoJSON is parsed using `feature` and `mesh` from topojson. React manages the component state, with D3 version 7 providing all geographic and scaling utilities.

Cities on World Map

This example displays a world map with city populations overlaid as semi-transparent circles. Country boundaries appear as gray landmasses with interior borders, alongside graticules and a sphere outline. The visualization uses D3’s geoNaturalEarth1 projection and geoPath to render the map, with a sqrt scale mapping city population to circle radius. Data comes from a CSV of world cities and TopoJSON land geometry, rendered as SVG within a React framework.

World Map with Cities

This visualization displays a world map with cities, where each city is represented by a circle scaled proportionally to its population. Using D3’s geoNaturalEarth1 projection and geoPath, the map renders landmasses, graticules, and country interiors from TopoJSON data, while city locations are projected from latitude and longitude coordinates. The React component employs the useWorldAtlas and useCities custom hooks to load data via d3.json and d3.csv, with d3.scaleSqrt mapping population to circle radius sizes.

World Map with cities

A world map visualization displays cities as semi-transparent circles, with circle area proportional to each city’s population. The map uses the Natural Earth projection via D3’s `geoNaturalEarth1` and `geoPath`, rendering graticules, land masses, and interiors from TopoJSON data. City coordinates and populations come from a CSV file, and the D3 `scaleSqrt` function maps population values to a maximum radius of 20 pixels.

World Map

This visualization displays a natural Earth projection world map with cities represented as semi-transparent circles sized by population. The map renders land masses in light gray with graticules and country borders overlaid. Built with React and D3 v6, it uses `geoNaturalEarth1` and `geoPath` for geographic projections, while `scaleSqrt` maps population data to circle radii. City coordinates and populations come from a CSV of world cities, and country boundaries derive from TopoJSON world-atlas data.

World Map

A world map visualization displays global cities as semi-transparent circles sized by population, overlaid on a natural Earth projection. The map renders landmasses, country interiors, and graticules using `d3.geoNaturalEarth1` and `d3.geoPath`. City coordinates and population data load via `d3.csv` from a world cities dataset, while geographic boundaries come from TopoJSON world-atlas data. React manages the asynchronous data loading and SVG rendering, with a square-root scale mapping population values to circle radii.

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.

Points on a Map

This visualization displays world cities as semi-transparent circles overlaid on a natural Earth projection map, with circle size encoding population via a square root scale. The map includes land masses, country borders, graticules, and a sphere outline. React manages the component structure, while D3 v7 handles geo projection and path generation through `d3.geoNaturalEarth1` and `d3.geoPath`. City data comes from a CSV loaded with `d3.csv`, and world geography uses TopoJSON from the world-atlas package, rendered as SVG.

Cities of the World

Cities of the World uses a natural Earth projection to display global population data as proportional circles. D3’s geoNaturalEarth1 and geoPath render landmasses, graticules, and sphere outlines, while a sqrt scale maps city populations to circle radii. The visualization loads world atlas topology from world-atlas and city CSV data, overlaying semi-transparent dots atop a muted map. React manages the SVG rendering, with d3.v5 providing the underlying geospatial and scaling utilities.
