This example displays a world map with cities sized by population. Natural Earth projection renders landmasses, graticules, and country borders using d3.geoPath. City points from a CSV dataset are projected onto the map and drawn as semi-transparent circles, with radius scaled by population using d3.scaleSqrt. React manages component state and rendering, while d3.v7 handles geographic calculations and data loading.

Points on a Map

This example displays a world map with city points scaled by population, using a natural Earth projection. The visualization layers graticules, land masses, and country borders beneath translucent teal circles. React components manage the rendering, while D3 utilities handle geographic projections and data loading. The size of each circle is determined by a square root scale mapping population values to a maximum radius of 15 pixels, with city data sourced from a CSV of world cities and geographic features from a TopoJSON world atlas.

Points on a Map

A world map displays cities scaled by population using semi-transparent teal circles. The visualization renders geographic landmasses, graticules, and interior borders via d3.geoPath with a Natural Earth projection, while a d3.scaleSqrt maps population values to circle radii. City locations are projected from latitude and longitude coordinates, and data is loaded from a CSV using d3.csv. The React application overlays these marks on an SVG canvas.

Points on a Map

A world map displays the geographic distribution of cities, with circles sized by population. The visualization uses a natural Earth projection with graticules, land masses, and country borders. Built with React and D3 v6, it employs `geoNaturalEarth1`, `geoPath`, and `geoGraticule` to render the SVG. City data comes from a CSV of world cities, while country boundaries derive from World Atlas TopoJSON. Circle radii are scaled using `scaleSqrt` based on population values.

Points on a Map

A world map rendered with a natural Earth projection displays cities as semi-transparent teal circles, with circle area scaled by population using a square-root scale. The visualization pairs D3’s geoNaturalEarth1 projection and geoPath with React components to draw landmasses, graticules, and country interiors. City coordinates and population data come from a CSV file, while geographic boundaries load via TopoJSON from the world-atlas package.

Points on a Map

This example displays a world map with points representing cities, with circle sizes scaled by population using a square-root scale. It shows a natural Earth projection with graticules and country boundaries overlaid. The visualization uses React to manage state and rendering, while D3 v5 provides `geoNaturalEarth1`, `geoPath`, `geoGraticule`, and `scaleSqrt`. City data comes from a CSV file, and world geography is loaded as TopoJSON. Circles are semi-transparent teal, plotted via projected longitude and latitude coordinates.

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 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

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`.
