This example shows a world map with over 50,000 cities plotted as semi-transparent points, using a Natural Earth projection. The visualization layers graticules, land masses, and country borders beneath the city data, with each city positioned via the `geoNaturalEarth1` projection and `geoPath`. Built with React and D3 v5, the code loads TopoJSON world atlas data and a CSV of city coordinates, rendering the map as SVG. City data comes from Simplemaps’ World Cities Database.

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 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 example displays a natural Earth projection world map with cities over 50,000 people plotted as small circles. The visualization uses D3 v5’s `geoNaturalEarth1` and `geoPath` for map geometry, with graticules and country borders styled via CSS. City coordinates are projected from latitude and longitude, and React manages the SVG rendering. Mouse hover changes a city’s fill color. Data comes from a Simplemaps world cities CSV, while country boundaries use the World Atlas TopoJSON.

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.

Fork of Fork of Points on a Map

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.

Fork of Points on a Map

This visualization shows a world map with dots marking cities whose population exceeds 50,000, plotted using the Natural Earth projection. The map displays country boundaries and graticules for geographic context, with cities rendered as semi-transparent circles. Built with React and D3 v5, the example uses `geoNaturalEarth1`, `geoPath`, and `geoGraticule` to project and draw geographic features, while TopoJSON provides land and interior mesh data. City coordinates come from a CSV file sourced from the Simplemaps World Cities Database, and all marks are rendered as SVG elements.

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 example shows a world map with cities of population over 50,000 plotted as small, semi-transparent dots. The map uses a natural Earth projection with graticules and country borders rendered via `geoPath` and `geoNaturalEarth1` from D3 v5. City positions are projected from latitude and longitude coordinates loaded from a CSV file, while country boundaries come from the World Atlas TopoJSON. The visualization is built as a React component, with SVG circles representing the cities and styling applied through CSS.

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.
