This example displays a world map with cities having populations over 50,000, sourced from the Simplemaps World Cities Database, overlaid on country boundaries from the World Atlas TopoJSON. The visualization uses React for component management and d3.geoNaturalEarth1 projection with d3.geoPath to render the sphere, graticules, land, and interiors. City points are projected and drawn as semi-transparent circles, using d3.csv for data loading and topojson’s feature and mesh functions to prepare the geographic data.

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 Points on a Map

This example displays a world map with circles marking cities whose populations exceed 50,000, using data from Simplemaps. The visualization renders geographic features with d3.geoPath and geoNaturalEarth1, including land masses, graticules, and country interiors. City coordinates are projected onto the SVG using the same projection, with semi-transparent circles indicating locations. The map is built with React hooks, d3.v5, and TopoJSON for world atlas data.

Fork of Points on a Map

This visualization shows a world map with cities of population greater than 50,000 plotted as semitransparent points. The map displays landmasses, graticules, and country interior boundaries. Using React for component structure, the code employs d3’s `geoNaturalEarth1` projection and `geoPath` to render geographic features, while city coordinates are projected and drawn as SVG circles. Data comes from the Simplemaps World Cities Database and World Atlas TopoJSON.

Fork of Points on a Map

This example renders a world map using a Natural Earth projection, showing cities with populations over 50,000 as semi-transparent points. The visualization loads geographic boundaries from World Atlas TopoJSON and city data from Simplemaps, then draws them with SVG paths and circles via `d3.geoNaturalEarth1`, `d3.geoPath`, and `d3.geoGraticule`. The React components manage data fetching through custom hooks, while D3’s `csv` and `json` methods load the datasets.

Fork of Points on a Map

This visualization shows a world map depicting cities with populations over 50,000, drawn as semi-transparent teal dots. The country boundaries and graticules are rendered using D3’s `geoNaturalEarth1` projection with `geoPath`, while the city positions are projected from latitude and longitude coordinates. The map uses a React front-end with `useWorldAtlas` and `useCities` hooks to load TopoJSON land data and CSV city data from Simplemaps, displaying everything as SVG elements.

Fork of Points on a Map

This visualization displays a world map with points marking cities that have populations exceeding 50,000, drawn from the Simplemaps World Cities Database. Using React and D3 v5, the example projects geographic coordinates onto an SVG canvas with the geoNaturalEarth1 projection and geoPath. The map includes land masses, country interiors, and graticules from World Atlas TopoJSON, while semi-transparent teal circles represent each city, revealing population clusters across continents.

Fork of Points on a Map

A world map displays cities with populations over 50,000 as semi-transparent teal dots, using the Natural Earth projection from `d3.geoNaturalEarth1`. The visualization renders landmasses, graticules, and interiors via `geoPath` and `geoGraticule`, with country boundaries from the World Atlas TopoJSON dataset and city coordinates from Simplemaps. Built with React, the code uses `d3.csv` for data loading and `topojson.feature` and `topojson.mesh` to process geographic topology, all rendered as SVG elements.

Fork of Points on a Map

This visualization shows a world map with cities rendered as semi-transparent teal circles, using data from the Simplemaps World Cities Database filtered to cities with populations exceeding 50,000. The map employs d3.geoNaturalEarth1 projection with d3.geoPath to draw land masses, country borders, graticules, and the sphere outline from TopoJSON world-atlas data. React components manage the SVG rendering, with d3.csv loading city coordinates and topojson.feature and topojson.mesh extracting geographic shapes for the base map.

Fork of Points on a Map

This example displays a world map with cities having populations over 50,000, plotted as semi-transparent teal circles. It uses a natural Earth projection via `geoNaturalEarth1` and renders both graticules and country interiors with `geoPath`. The map is built with React, loading geographic data from World Atlas TopoJSON and city coordinates from a Simplemaps CSV. City positions are projected using `[d.lng, d.lat]` to determine circle placement within an SVG.
