This example visualizes a world map with circles sized by city population, focusing on cities with populations exceeding 50,000. The map uses a Natural Earth projection rendered with `geoNaturalEarth1` and `geoPath`, while city points are positioned via the projection and scaled using `scaleSqrt` for their radius. Data is sourced from Simplemaps and world-atlas TopoJSON, with graticules and polished land boundaries. The visualization is built with React, leveraging `d3.csv` for data loading and `topojson.mesh` for interior boundaries.

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 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.

Fork of Sized Points on a Map

This visualization displays a world map with circles sized proportionally to city populations, using a square root scale to encode population values. The map includes land masses, country borders, graticules, and a sphere outline, rendered with `geoNaturalEarth1` projection and `geoPath` from d3. City data comes from the Simplemaps World Cities Database, filtered to populations above 50,000. The React app loads TopoJSON world atlas data and CSV city data, then renders SVG circles with transparency over the geographic features.

Fork of Sized Points on a Map

A map visualization plots world cities with populations exceeding 50,000 as sized points, using a square-root scale to encode population via circle radius. The map uses `geoNaturalEarth1` projection with `geoPath` for land, graticules, and country interiors. City data comes from Simplemaps’ World Cities Database, rendered in React with SVG circles. The visualization is built with d3.v5, featuring a clean, light-styled map with semi-transparent teal circles showing population distribution globally.

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 over 50,000 in population, represented by semi-transparent circles scaled by population using a sqrt scale. It uses React for component structure and d3’s geoNaturalEarth1 projection, geoPath, and geoGraticule to render land, country interiors, and graticule lines from World Atlas TopoJSON data. City coordinates and populations come from a CSV loaded via d3.csv, with circle radii capped at 15 pixels.

Fork of Sized Points on a Map

This visualization presents a world map where each circle represents a city with a population exceeding 50,000, sourced from the Simplemaps World Cities Database. The circles’ radii are scaled using a square-root scale (`scaleSqrt`) based on population, with a maximum radius of 15 pixels. The map uses `d3.geoNaturalEarth1` and `d3.geoPath` to render country landmasses and interiors from World Atlas TopoJSON, plus graticules for a polished look. The visualization is built with React and SVG, loading data via custom `useWorldAtlas` and `useCities` hooks that fetch JSON and CSV respectively.

Fork of Sized Points on a Map

A world map displays cities with populations over 50,000 as semi-transparent teal circles, sized using a square-root scale that maps population to radius. The map includes natural Earth landmasses with graticules and country interiors, styled in muted grays. The visualization is built with React, using d3's `geoNaturalEarth1` projection and `geoPath` for rendering, while city data comes from Simplemaps and country boundaries from the World Atlas TopoJSON.

Fork of Sized Points on a Map

This example presents a world map with a point for every city whose population exceeds 50,000, using a square-root scale to size each circle proportionally to its population. The map is rendered with SVG using React and D3 v5, employing `geoNaturalEarth1` for the projection and `geoPath` for drawing land, interiors, and graticules. City data comes from the Simplemaps World Cities Database, while country boundaries derive from World Atlas TopoJSON, with circles styled in teal at partial opacity.
