Forked from Polished World Map

This example visualizes global population data by plotting cities as semi-transparent circles on a Natural Earth projected world map. A square-root scale maps each city’s population to circle radius, with the largest cities appearing most prominent. The visualization uses React for component structure and D3 v5 APIs including `geoNaturalEarth1`, `geoPath`, `geoGraticule`, and `scaleSqrt`. Country boundaries and graticules come from the World Atlas TopoJSON, while city coordinates and populations are loaded from a clean CSV dataset.

A world map showing country boundaries from World Atlas TopoJSON, polished for visual style, including graticules.

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`.

Points on a map

This example visualizes global population distribution by plotting circles for cities on a natural Earth projection map. Circle radius encodes population using a square-root scale, with semi-transparent styling to show overlapping urban areas. The visualization uses React for component rendering, D3 v5 for geographic projections (`geoNaturalEarth1`), path generation (`geoPath`), and graticule creation, alongside TopoJSON to process world-atlas land and interior boundary data. City coordinates and populations come from a CSV dataset loaded via D3’s `csv` utility.

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 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 world map

This visualization displays world cities as scaled circles on a natural Earth projection, with marker size encoding population using a square-root scale. The map renders land masses, graticules, and country borders in muted grays, while semi-transparent teal points overlay major urban centers. Built with React and D3 v7, it uses `geoNaturalEarth1` with `geoPath` for geographic projection, TopoJSON for world atlas data, and `scaleSqrt` to map population values to circle radii. City coordinates and populations come from a CSV dataset loaded via D3’s `csv` function.

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 World Map

This example displays global population distribution by plotting cities as semi-transparent circles on a natural Earth projection, with circle size scaled by population using a square-root scale. The visualization uses React for component structure, D3 v7’s `geoNaturalEarth1` and `geoPath` for map rendering, and TopoJSON to load world country boundaries. City coordinates and populations come from a CSV dataset, projected onto the map with `projection([lng, lat])`.

Points on a Map

This visualization displays a world map with cities plotted as scaled circles representing population. The map uses the Natural Earth projection with graticules, country boundaries, and interiors rendered via D3's `geoPath` and `geoNaturalEarth1` projection. City positions come from a CSV file, and circle radii are scaled using D3's square-root scale (`scaleSqrt`) based on population data. The visualization is built with React and renders SVG marks, including land masses, a sphere outline, and graticule lines, all styled with a clean grayscale aesthetic.
