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.

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.

This example shows a world map with cities whose populations exceed 50,000, rendered as semi-transparent circles sized by the square root of their population. The map includes landmasses, country interiors, graticules, and a background sphere, all drawn using `d3.geoPath` with the Natural Earth projection (`geoNaturalEarth1`). City data comes from a Simplemaps CSV loaded via `d3.csv`, while country boundaries are derived from World Atlas TopoJSON processed with `topojson.feature` and `mesh`. The visualization is built with React and D3 v4, using `scaleSqrt` to map population values to circle radii.

This example displays a world map with cities whose populations exceed 50,000, using circles sized by population via a square-root scale. It renders country boundaries and graticules using `d3.geoPath` with TopoJSON data from World Atlas, while city locations come from the Simplemaps World Cities Database. The React app uses `useWorldAtlas` and `useCities` custom hooks to load data, then passes a size scale and value accessor to a `Marks` component that draws the SVG output.

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 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 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.

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.

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.
