This example displays a world map with circles sized according to city population, showing cities with over 50,000 residents. The visualization uses a natural Earth projection via `d3.geoNaturalEarth1` and renders geographic features with `d3.geoPath`, including graticules and country boundaries from World Atlas TopoJSON. City data comes from Simplemaps’ World Cities Database, and circle radii are scaled using `d3.scaleSqrt`. The React component structure, SVG rendering, and D3 v5 APIs are used to create the map.

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.

Fork of Sized Points on a Map

This example displays a world map with circles sized by population for cities exceeding 50,000 residents. The visualization uses d3.geoNaturalEarth1 and d3.geoPath to render landmasses, graticules, and country interiors, while circles are positioned with the projection and scaled using d3.scaleSqrt. City data comes from a CSV loaded via d3.csv, and country boundaries derive from World Atlas TopoJSON processed with topojson.feature and topojson.mesh. The React component structure manages state with hooks and renders SVG elements.

Fork of Sized Points on a Map

This example displays a world map with cities exceeding 50,000 in population, using circles sized and colored by population via a square-root scale. The map uses a natural Earth projection with graticules and land boundaries from the World Atlas TopoJSON, styled with CSS. Data is loaded from Simplemaps' World Cities Database using d3.csv. The visualization is built with React, rendering SVG paths for geography and circles for cities, using d3.geoNaturalEarth1, d3.geoPath, and d3.geoGraticule for the map projection and graticule lines.

Sized Points on a Map

This example visualizes global population distribution by rendering sized circles for cities with populations exceeding 50,000. The visualization uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to draw countries, graticules, and interiors from World Atlas TopoJSON data. City positions are projected from latitude and longitude coordinates, with circle radii scaled by population using `d3.scaleSqrt`. The React component fetches city data from a Simplemaps World Cities CSV.

Sized Points on a Map

A world map displays cities with populations over 50,000, using scaled circle radius to encode population size. The visualization combines a Natural Earth projection rendered through d3.geoPath with graticules and country boundaries from World Atlas TopoJSON. City data comes from Simplemaps’ World Cities Database, loaded via d3.csv and projected onto the map. Circle sizes use d3.scaleSqrt for area encoding, with React managing the SVG rendering and d3.v5 providing the geographic and data utilities.

Sized Points on a Map

This example displays cities with populations over 50,000 as sized points on a world map, using a square-root scale to encode population by circle radius. The map renders with the `geoNaturalEarth1` projection and `geoPath` in React, showing graticules and country boundaries from World Atlas TopoJSON. City data comes from Simplemaps via CSV, loaded with `d3.csv`. Circles are drawn with SVG, styled with a teal fill and 0.3 opacity.

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.

This example displays a world map with circles sized by population for cities exceeding 50,000 residents. It uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to render landmasses, graticules, and interiors. City data is loaded from a CSV using `d3.csv`, with circle radii scaled by a square root scale (`d3.scaleSqrt`). The visualization is built with React and rendered as SVG, styled with soft teal, semi-transparent points.
