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.

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 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

A world map displays cities with populations over 50,000 as semi-transparent circles sized proportionally to population using a square-root scale. The visualization uses d3.geoNaturalEarth1 projection, d3.geoPath, graticules, and country boundaries from World Atlas TopoJSON, with city data from a Simplemaps CSV. React manages state and rendering, while d3.scaleSqrt maps population values to circle radii. The SVG output includes styled landmasses, sphere background, and interior borders.

Fork of Sized Points on a Map

This visualization displays a world map with cities over 50,000 population represented by semi-transparent circles, whose radii encode population via a square-root scale. Country boundaries, graticules, and the sphere outline are drawn using `d3.geoNaturalEarth1` and `d3.geoPath` in SVG. React manages the component state, fetching city data from a CSV via `d3.csv` and country topology from the World Atlas TopoJSON using `d3.json` and `topojson.feature`. The squared-sized points highlight population distribution across the globe.

Fork of Sized Points on a Map

This example displays a world map with cities over 50,000 inhabitants, where each city is represented by a semi-transparent circle sized proportionally to its population using a square-root scale. The map renders in SVG via React, using `d3.geoNaturalEarth1` for projection and `d3.geoPath` to draw landmasses, graticules, and country boundaries from TopoJSON. City coordinates and population values come from a CSV dataset, with circle radii mapped from population via `scaleSqrt`.

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.

Fork of Sized Points on a Map

A world map displays cities with populations over 50,000, with circle size scaled by population using a square-root scale from d3-scale. The visualization renders geographic features—landmasses, country interiors, the sphere, and graticules—via d3.geoNaturalEarth1 and d3.geoPath in an SVG. City coordinates are projected from latitude and longitude, while data comes from a CSV of world cities and the World Atlas TopoJSON, all styled with translucent teal circles.
