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

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 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 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

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.

Cities on the World Map

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 Cities Map

This visualization displays a world map with circles marking cities that have populations exceeding 50,000, sourced from the Simplemaps World Cities Database. The map uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to render landmasses, graticules, and interiors in SVG. Circle radii are scaled proportionally to population using `d3.scaleSqrt`. The visualization is built with React, D3 v5, and TopoJSON, loading world atlas data from `world-atlas@2.0.2`.

World Map

This visualization displays a world map with the population of major cities represented by proportional circles. Circles are sized using a square root scale based on each city’s population, overlaid on a gray landmass with graticules and interior borders. Built with React and D3 v5, it uses `geoEqualEarth`, `geoPath`, and `geoGraticule` for the map projection, while city data comes from a CSV file and world geography from TopoJSON.
