This visualization displays the population of cities as circles sized on a geographic map. It uses a Mercator projection to position each city, with the circle radius determined by a square-root scale applied to population data from the Sense Your City dataset. The map is rendered as SVG paths for countries and their interiors, with the circles overlaid in a semi-transparent teal color. The code leverages D3’s `geoMercator`, `geoPath`, and `scaleSqrt` functions within a React framework, loading both world atlas topology and CSV city data from external URLs.

Using Size

This visualization displays a world map with circles sized by city population, using a square-root scale to encode magnitude with area. The map renders landmasses, interiors, graticules, and the sphere via d3.geoNaturalEarth1 and d3.geoPath, while d3.scaleSqrt maps population values to circle radii up to 15 pixels. Data comes from a CSV of world cities loaded with d3.csv, and the map uses TopoJSON from world-atlas. React manages the SVG rendering, with circles styled semi-transparent teal.

Sized Points on a Map

This visualization displays global cities with populations exceeding 50,000 as semi-transparent circles sized proportionally to population using a square-root scale. The map uses a natural Earth projection, with country boundaries, interiors, and graticules rendered via d3.geoPath from TopoJSON world-atlas data. City coordinates are projected using d3.geoNaturalEarth1, with population data loaded from a Simplemaps CSV. The React component applies the size scale to each circle’s radius, creating an immediate visual comparison of urban population distribution across continents.

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

This visualization displays global cities with populations over 50,000 as semi-transparent circles on a natural Earth projection. Circle radius encodes population magnitude using a square-root scale, making larger metropolitan areas visually prominent. The map renders country boundaries, graticules, and sphere outlines via d3.geoNaturalEarth1, d3.geoPath, and d3.geoGraticule, while React manages the SVG markup. City data originates from Simplemaps, loaded through d3.csv, and geographical boundaries come from World Atlas TopoJSON, processed with topojson.feature and topojson.mesh.

Using Size

A world map displays cities with populations over 50,000, using circle size to encode population magnitude with a square-root scale. The map includes country boundaries, graticules, and a sphere outline, rendered as SVG via React. It uses `d3.geoNaturalEarth1` and `d3.geoPath` for projection, with data from the Simplemaps World Cities Database and World Atlas TopoJSON, processed through `topojson.feature` and `mesh`.

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 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

This visualization displays global cities as sized points on a natural Earth projection map, with circle radii scaled proportionally to population using d3.scaleSqrt. The map renders landmasses, graticules, and country interiors as SVG paths generated via d3.geoPath, while city positions are projected from longitude and latitude coordinates. The React component loads world atlas TopoJSON and city CSV data asynchronously, then applies semi-transparent teal circles to highlight population distribution across continents.
