This example displays a world map with points sized by city population, revealing geographic population clusters. The map uses an equirectangular projection with graticules and country boundaries. The visualization is built with React and D3 v5, using d3.geoNaturalEarth1 for projection, d3.geoPath for rendering geographies, and d3.scaleSqrt for encoding population values as circle radii. City data comes from a CSV with 50,000+ populated places, while country boundaries derive from the World Atlas TopoJSON. Semi-transparent circles preserve readability over dense areas.

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.

Sized Points on a Map

This visualization displays a world map with circles sized by city population, using a square-root scale to encode magnitude. The map includes landmasses, graticules, and country interiors rendered via d3.geoPath and a geoNaturalEarth1 projection. City coordinates and population data come from a CSV dataset, with React managing the component lifecycle and d3.v5 handling data loading and scaling. Semi-transparent teal circles are positioned using the projection and scaled up to a maximum radius of 15 pixels.

Sized Points on a Map

A world map displays cities with populations exceeding 50,000, using sized points to encode population via a d3.scaleSqrt square-root scale. The visualization renders a Natural Earth projection using d3.geoNaturalEarth1 and d3.geoPath, with graticules and country boundaries from World Atlas TopoJSON. City data from Simplemaps is plotted as semi-transparent circles. The React-based code loads TopoJSON and CSV data asynchronously, then applies d3.geoPath to project coordinates and d3.scaleSqrt to determine circle radii.

Points on a Map

This example displays a world map with city points scaled by population, using a natural Earth projection. The visualization layers graticules, land masses, and country borders beneath translucent teal circles. React components manage the rendering, while D3 utilities handle geographic projections and data loading. The size of each circle is determined by a square root scale mapping population values to a maximum radius of 15 pixels, with city data sourced from a CSV of world cities and geographic features from a TopoJSON world atlas.

Sized Points on a Map

A world map displays cities with populations over 50,000 as semitransparent circles, sized proportionally to their population using a square-root scale. The visualization uses React for the user interface and D3 v5’s `geoNaturalEarth1` projection with `geoPath` to render country boundaries, graticules, and a sphere backdrop. City data comes from Simplemaps, while country shapes come from World Atlas TopoJSON. Circles are positioned via the projection and sized using `scaleSqrt` from D3, with opacity set through CSS.

Sized Points on a Map

This visualization displays a world map with points sized proportionally to city populations, showing cities with over 50,000 residents. It uses d3.geoNaturalEarth1 for projection and d3.geoPath for rendering country boundaries and graticules. City coordinates and populations come from a CSV loaded from Simplemaps, while country shapes use TopoJSON from World Atlas. The point radii are scaled with d3.scaleSqrt, and React manages component rendering.

Sized Points on a Map

A world map displays cities with populations over 50,000 as semi-transparent circles, with radius encoding population magnitude via a square-root scale. The visualization uses a Natural Earth projection and geo paths from d3.geoPath to render land, graticules, and country boundaries from World Atlas TopoJSON. City coordinates are projected using d3.geoNaturalEarth1, with data sourced from the Simplemaps World Cities Database. The React-based SVG rendering leverages D3 v5 for geographic and scaling operations, presenting city population distributions across the globe.

Sized Points on a Map

This example displays a world map with sized points representing cities, where the circle radius encodes each city's population using a square root scale with a maximum radius of 15 pixels. It renders the Natural Earth projection via d3.geoPath, including graticules and land boundaries from Topojson World Atlas data. City coordinates and population values come from a CSV dataset, and the visualization uses React for component structure alongside D3 v6 for geographic projections and scales, with all marks drawn as SVG elements.
