This example visualizes a world map with dots marking cities whose population exceeds 50,000. The city locations are plotted as semi-transparent teal circles over a natural Earth projection, with landmasses, graticules, and country interiors rendered in gray tones. The visualization is built with React and uses D3's `geoNaturalEarth1`, `geoPath`, and `geoGraticule` functions to project geographic data from the World Atlas TopoJSON. City coordinates come from the Simplemaps World Cities Database, accessed via a CSV file, and are projected onto the map using D3's projection method.

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.

This example displays a world map with dots marking cities that have populations exceeding 50,000. The map uses a Natural Earth projection and renders land masses, graticules, and country borders as SVG paths. City positions are projected from longitude and latitude coordinates using `d3.geoPath` with `geoNaturalEarth1`, and each city is drawn as a semi-transparent circle. The visualization loads world atlas TopoJSON data and a city CSV dataset, with React managing the component lifecycle.

Points on a Map

A natural Earth projection world map displays cities with populations over 50,000 as semi-transparent teal dots, layered over light gray landmasses and graticules. The visualization uses React with D3 v5, employing `geoNaturalEarth1` and `geoPath` for the projection, while city coordinates are converted through the projection function to position SVG circles. City data originates from Simplemaps' World Cities Database, with country boundaries from the World Atlas TopoJSON, and the map includes subtle interior country borders for geographic context.

This example displays city locations as semi-transparent teal dots on a natural Earth projection world map, highlighting urban centers with populations exceeding 50,000. The visualization uses React for component structure and D3 v5’s `geoNaturalEarth1` projection with `geoPath` to render land masses, country boundaries, graticules, and a sphere outline. City coordinates from the Simplemaps World Cities Database are projected using `projection([d.lng, d.lat])` into SVG circles. The map background and land fill are styled via CSS, with graticules providing geographic reference lines.

A world map displays cities with population over 50,000 as semi-transparent teal dots, projected using the Natural Earth projection. The visualization layers graticules, land masses, and country borders from World Atlas TopoJSON, with city coordinates from a Simplemaps CSV. React manages the component state while D3’s `geoNaturalEarth1`, `geoPath`, and `geoGraticule` handle the geographic rendering, and `csv` and `json` load the external datasets.

Points on a Map

A world map displays cities with populations over 50,000 as semi-transparent dots. The visualization uses a natural Earth projection via d3.geoNaturalEarth1 and renders geographic features with d3.geoPath, including land masses and graticules. City coordinates are projected from latitude and longitude into SVG circle positions. The map loads country boundaries from World Atlas TopoJSON and city data from a Simplemaps CSV, with React managing the data-fetching hooks and rendering the SVG marks.

Points on a Map

A map of the world displays cities with populations over 50,000 as small translucent dots. The visualization uses a React component with D3’s `geoNaturalEarth1` projection and `geoPath` to render country boundaries, graticules, and the sphere outline. City coordinates are projected from latitude and longitude, with data loaded via `d3.csv` from the Simplemaps World Cities Database, while land and interior borders come from TopoJSON in the World Atlas TopoJSON dataset.

Points on a Map

This visualization displays world cities with populations exceeding 50,000 as semi-transparent teal points on an SVG map. The map uses a Natural Earth projection via d3.geoNaturalEarth1, with landmasses, graticules, and interiors rendered using d3.geoPath. City locations are projected from latitude and longitude coordinates, then drawn as small circles. The underlying city data comes from Simplemaps, while country boundaries come from the World Atlas TopoJSON, both loaded asynchronously with d3.csv and d3.json. The React component structure uses custom hooks for data fetching.
