This example displays a world map with circles sized proportionally to city populations, using data from the Simplemaps World Cities Database. The map renders geographic features with d3.geoNaturalEarth1, d3.geoPath, and d3.geoGraticule, while country boundaries load from World Atlas TopoJSON. City points are placed via projection coordinates and scaled with d3.scaleSqrt, all built within a React component using SVG. The visualization includes graticules and styled land, sphere, and interior paths for a polished cartographic look.

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 example displays a world map with circles sized proportionally to city populations, using a square root scale to encode population values. The visualization renders geographic landmasses, graticules, and interiors via D3’s `geoNaturalEarth1` projection and `geoPath`, while city points are positioned with the same projection. Data comes from a Simplemaps CSV of cities with populations over 50,000, and country boundaries from TopoJSON’s world-atlas. React manages the component state, and SVG circles use a max radius of 15 pixels with a teal fill.

Sized Points on a Map

This visualization displays a world map with circles sized proportionally to city populations, using data from Simplemaps and country boundaries from World Atlas TopoJSON. The map is rendered with SVG and React, employing d3.geoNaturalEarth1 and d3.geoPath for geographic projections, while a d3.scaleSqrt maps population values to circle radii. The visualization includes graticules and land/interior boundaries, with semi-transparent teal circles marking cities with populations over 50,000.

Sized Points on a Map

This example presents a world map with cities sized proportionally to their population, using a square-root scale to encode the data. The visualization renders geographic features like landmasses, graticules, and country boundaries using `geoNaturalEarth1` and `geoPath`, while city points are drawn as SVG circles positioned via the projection. The map is built with React and D3 v5, pulling city data from a CSV of the Simplemaps World Cities Database and country topology from World Atlas TopoJSON.

Sized Points on a Map

This example shows a world map with cities represented as sized points, where circle radius encodes each city’s population using a square-root scale. It uses d3.geoNaturalEarth1 and d3.geoPath to render land, graticules, and interiors from World Atlas TopoJSON, while city data comes from a Simplemaps CSV loaded via d3.csv. The React component passes a d3.scaleSqrt to SVG circles, with rendering handled in React and styling via CSS.

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.

Sized Points on a Map

A world map displays cities with populations exceeding 50,000, using circle size to encode population magnitude. The visualization renders geographic context via d3.geoNaturalEarth1 projection and d3.geoPath for landmasses, graticules, and country boundaries. City positions are projected from latitude and longitude coordinates, with circle radii scaled by a d3.scaleSqrt function representing population values. Data comes from the Simplemaps World Cities Database and World Atlas TopoJSON, while React components manage the SVG rendering.
