This interactive world map displays all cities with populations exceeding 50,000, using circle size to encode population magnitude through a square-root scale. Built with React and D3 v7, the visualization renders SVG paths from TopoJSON world atlas data alongside city coordinates from a CSV dataset. The natural Earth projection draws graticules and styled landmasses, while hover tooltips reveal country, city name, and formatted population using d3.format.

AI-generated description

A world map showing cities with population greater than 50,000. City data from Simplemaps: World Cities Database.

Country boundaries from World Atlas TopoJSON, polished for visual style, including graticules.

world map w/ cities

This example presents a world map visualization of cities with populations exceeding 50,000. It uses a React framework with SVG rendering, employing d3-geo-projection’s geoNaturalEarth1 projection and d3-geo’s geoPath to draw landmasses, country boundaries, graticules, and geographic lines. City locations are plotted as circles from Simplemaps’ World Cities Database, while country and land data come from World Atlas TopoJSON. The visualization includes hover tooltips showing country names, with styling applied through CSS.

world map w/ cities

This visualization displays a world map with cities whose populations exceed 50,000, using a natural Earth projection that spins to reveal different hemispheres. The map incorporates country boundaries, interior borders, graticules, and geographic lines, with land areas filled by an animated pattern. City markers are sized by population using a square-root scale, while country boundaries include tooltips on hover. The project uses React with D3’s `geoNaturalEarth1`, `geoPath`, and `geoGraticule`, sourcing city data from Simplemaps and country shapes from World Atlas TopoJSON, all rendered as SVG elements.

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 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.

Untitled

A world map displays cities with populations exceeding 50,000 as semi-transparent teal circles scaled by population size. The visualization uses d3.geoNaturalEarth1 for projection and d3.geoPath to render landmasses, country interiors, and graticules from World Atlas TopoJSON data. City coordinates and populations are loaded via d3.csv, with circles positioned using the projection and sized through a linear scale. The SVG is built in React, with static styling applying a light fill to land and subtle borders.

World Map - React & D3

This map visualization displays global cities with scaled square-root population marks overlaid on a land-based world map. Built with React and D3 v5, it renders an SVG projection using `d3.geoMercator()` and `d3.geoPath` with graticules, land features, and interior boundaries. City data comes from a CSV file, and population values drive symbol sizing via `d3.scaleSqrt`.

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

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.
