A world map displays cities as semi-transparent teal circles, with each circle’s radius scaled by the square root of the city’s population. The basemap is rendered using `d3.geoNaturalEarth1` and `d3.geoPath` from the D3 v7 library, with graticules and land interiors styled via CSS. City coordinates from a CSV file are projected and drawn as SVG circles, sized using D3’s scaleSqrt. The code integrates React for UI management and fetches topology data from the World Atlas TopoJSON.

Points on a Map with Size

A world map displays cities as semi-transparent circles, with circle size encoding each city’s population using a square-root scale. The map renders geographic landmasses, graticules, and country borders from the World Atlas TopoJSON, projected with `d3.geoNaturalEarth1`. City data loads from a CSV via `d3.csv`, while React components manage state and render the SVG, using `d3.geoPath` to draw map features and `d3.scaleSqrt` for sizing.

Points on a Map with Size

A world map displays city populations as semi-transparent circles, with point size encoding each city’s population value via a square-root scale. The visualization uses the Natural Earth projection via d3.geoNaturalEarth1 and renders graticules, land masses, and country interiors with d3.geoPath. City coordinates are projected from longitude and latitude, while the map geometry comes from World Atlas TopoJSON processed with topojson.feature and topojson.mesh. React components manage the SVG rendering, and the data is loaded asynchronously from a CSV of world cities using d3.csv.

Points on a Map

A world map displays cities as semi-transparent teal circles, sized proportionally to population using a square-root scale with a maximum radius of 15 pixels. The visualization combines a Natural Earth projection with graticules, land masses, and country borders, rendered via `d3.geoPath` and TopoJSON from the world-atlas dataset. Point positions are calculated using `d3.geoNaturalEarth1`, while city data comes from a CSV loaded with `d3.csv`. React manages the component state, and SVG circles represent each urban center.

Points of a Map with Size

A world map renders populated cities as translucent circles, with point size encoding each city’s population through a square-root scale. Using D3’s `geoNaturalEarth1` projection and `geoPath`, the map displays landmasses, graticules, and country borders, while React components load data via the `useWorldAtlas` and `useCities` hooks. City coordinates are projected and drawn as SVG circles, with population data sourced from a CSV file and geographic boundaries from TopoJSON.

Points on a Map

A world map displays cities as semi-transparent, radius-scaled circles proportional to population, using a Natural Earth projection. The visualization, built with React and D3 (v5), renders SVG paths for land, graticules, and sphere outlines via `geoPath`, while circles are projected using `geoNaturalEarth1`. City data comes from a CSV of world cities, and the map’s geographic basemap is provided by the `world-atlas` TopoJSON, processed through `topojson.feature` and `topojson.mesh`.

Sized Points on a Map

A world map displays cities as semi-transparent teal circles sized by population using a square-root scale. The map includes land areas, country borders, graticules, and a natural Earth projection. Built with React and D3 v5, it projects geographic coordinates using `geoNaturalEarth1` and `geoPath`, draws features from World Atlas TopoJSON, and loads city data from a CSV file. Circle radii are mapped from population values via `scaleSqrt`.

Points on a Map

A world map displays cities as semi-transparent teal circles, with circle size encoding population via a square-root scale. The map uses a Natural Earth projection with land masses, graticules, and country interiors rendered via `geoPath` and `geoGraticule` from D3. The React app loads TopoJSON from World Atlas and CSV city data, then projects coordinates through `geoNaturalEarth1` to position the SVG circles.

Sized Points on a Map

A world map displays cities with populations over 50,000 as semi-transparent teal points, sized proportionally to population using a square-root scale. The visualization uses d3.geoNaturalEarth1 and d3.geoPath to render landmasses, graticules, and sphere geometry from World Atlas TopoJSON, while city coordinates are projected from a Simplemaps CSV. React components manage the asynchronous data loading via d3.csv and d3.json, with SVG circles positioned by the projection and radii mapped from the scale.
