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

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

This example visualizes the global distribution of cities, with circle size encoding each city’s population using a square-root scale. A Natural Earth projection renders landmasses, graticules, and country borders via `d3.geoPath` and `geoNaturalEarth1`, while city points are positioned using the same projection. Data comes from a CSV of world cities and TopoJSON world-atlas geometry, all drawn as SVG within a React component.

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.

Points on a Map

This visualization displays a world map with circles representing the populations of cities, scaled using a square root scale from D3. The map, rendered as SVG in a React app, uses the D3 `geoNaturalEarth1` projection to place points. Geographic data comes from the world-atlas TopoJSON via `topojson.feature` and `topojson.mesh`, while city data loads from a CSV. The graticule, sphere, and land outlines are styled via CSS, and the semi-transparent teal circles have opacity set to 0.3.

Points on a Map

This example displays world cities as semi-transparent circles on a natural Earth projection, with circle size encoding each city's population. The map renders landmasses and country borders from the world-atlas TopoJSON dataset, with graticules and a sphere outline providing geographic context. Using React hooks to load data asynchronously, the visualization applies d3.geoNaturalEarth1 and d3.geoPath for projection, d3.scaleSqrt for radius scaling, and maps city coordinates through the projection to position SVG circles.

Points on Map

This visualization displays a natural Earth map with circles representing global cities, where each circle’s radius is scaled by population using a square root scale. The map is rendered as SVG through React, using d3.geoNaturalEarth1 for projection and d3.geoPath for drawing land, graticules, and country borders. City data comes from a CSV of world cities, while the map topology is loaded from world-atlas TopoJSON.

Points on a map

This visualization displays a world map with city points scaled by population. Country outlines and graticules are rendered using d3.geoPath and the geoNaturalEarth1 projection, with city populations mapped to point radii via a d3.scaleSqrt. Data comes from a CSV of world cities and TopoJSON world atlas features, rendered as SVG within a React application.

Points on a Map

This example visualizes global population distribution by plotting cities as semi-transparent points on a natural Earth projection map. The map includes graticules, landmasses, and country borders, with each circle’s radius scaled proportionally to its city’s population using `d3.scaleSqrt`. The visualization uses `d3.geoNaturalEarth1`, `d3.geoPath`, and `d3.geoGraticule` for geographic rendering, with React managing state and SVG elements for drawing. The underlying city data comes from the Data Canvas Sense Your City dataset, loaded via `d3.csv`, while world topology is fetched from the World Atlas TopoJSON file and processed with `topojson.feature` and `topojson.mesh`.
