This map visualization displays world cities as semi-transparent circles sized by population on a Natural Earth projection. Built with React and D3 v6, it uses `d3.geoNaturalEarth1` and `d3.geoPath` to render land masses, graticules, and country interiors from TopoJSON data, while `d3.scaleSqrt` maps city populations to circle radii. City coordinates from a CSV dataset are projected onto the SVG canvas, with D3’s `csv` loader fetching the data asynchronously.

AI-generated description

Loading topojson and convert in memory to geojson, then render to make a map.

Add points to the map.

Points on a Map

This example renders a world map with city populations using a natural Earth projection. The visualization uses D3’s `geoNaturalEarth1` projection and `geoPath` to draw landmasses, graticules, and country interiors, while scaled circles overlaid onto the map encode each city’s population with a square-root scale. The data comes from the Data Canvas Sense Your City dataset, loaded via `d3.csv`. The React application asynchronously fetches the world atlas and city data, then renders the visualization as an SVG.

Points on a Map

This map visualization plots world city populations using circles projected onto a Natural Earth base. It uses D3 v5’s `geoNaturalEarth1` and `geoPath` to render landmasses, graticules, and country interiors, while a sqrt scale maps population values to circle radii. The React-based component loads city data from a CSV and renders SVG marks, using a world atlas TopoJSON for geographic context.

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`.

Points on a Map

This example displays world cities as scaled circles on a natural Earth projection, with each circle’s radius proportional to its population. The map renders landmasses, graticules, and interiors using `d3.geoPath` and `d3.geoNaturalEarth1`, while the city points are drawn as SVG circles with a square-root scale for size encoding. The visualization loads geographic topology from `world-atlas` and city CSV data via `d3.csv`, using React hooks (`useState`, `useEffect`) to manage the asynchronous data fetching and triggering re-renders.

Points on a map

This example displays a world map with cities plotted as semi-transparent circles, where circle size reflects each city’s population. It uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to render land, graticules, and country borders from TopoJSON data. City coordinates and populations come from a CSV loaded with `d3.csv`, and circle radii are scaled with `d3.scaleSqrt`. The visualization is built with React hooks for data fetching and renders as SVG.

Points on a Map

This visualization maps global cities as points on a natural Earth projection, with circle size encoding population. It uses React for rendering SVG elements, D3 v5 for geographical projections and scales, and loads world atlas TopoJSON data plus city CSV data from external URLs. The code employs d3.geoPath, d3.geoNaturalEarth1, and d3.geoGraticule to draw landmasses, graticules, and sphere outlines, while d3.scaleSqrt maps population values to circle radii.

Points on a Map

A world map rendered with a Natural Earth projection displays global cities as semi-transparent circles, sized by population. The visualization uses React and D3 v7, with `geoNaturalEarth1` and `geoPath` to draw landmasses, graticules, and country interiors from TopoJSON data. City coordinates are projected and plotted as SVG circles, with a sqrt scale mapping population to radius. Data comes from a CSV of world cities loaded via `d3.csv`.

Points on a Map

This visualization displays world cities as semi-transparent circles overlaid on a natural Earth projection map, with circle size encoding population via a square root scale. The map includes land masses, country borders, graticules, and a sphere outline. React manages the component structure, while D3 v7 handles geo projection and path generation through `d3.geoNaturalEarth1` and `d3.geoPath`. City data comes from a CSV loaded with `d3.csv`, and world geography uses TopoJSON from the world-atlas package, rendered as SVG.
