This example shows a world map with points for cities, using a natural Earth projection and graticules for geographic context. The visualization layers country land masses and interiors from World Atlas TopoJSON, with semi-transparent circles positioned via `d3.geoNaturalEarth1` and `d3.geoPath`. City data comes from a CSV loaded through `d3.csv`, and the React-based component structure uses hooks like `useWorldAtlas` and `useCities` to manage asynchronous data fetching.

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 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.

Fork of Points on a Map

A world map displays cities with populations exceeding 50,000 as small teal circles, projected using the Natural Earth projection via `d3.geoNaturalEarth1` and rendered as SVG paths with `d3.geoPath`. Country boundaries and graticules come from World Atlas TopoJSON data, styled with muted gray fills and strokes. React fetches city coordinates from a CSV using `d3.csv` and renders them as `circle` elements, while `topojson`’s `feature` and `mesh` functions process the atlas topology for landmasses and interior borders.

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 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 example displays a natural Earth projection world map with graticules and country boundaries, overlaid with small semi-transparent teal dots representing cities exceeding 50,000 in population. The map is rendered as SVG using React, with D3’s `geoNaturalEarth1` projection, `geoPath`, and `geoGraticule` for the geographic features. City coordinates are projected from latitude and longitude into screen positions, and the underlying data comes from Simplemaps’ World Cities Database, while land and interior boundaries derive from the World Atlas TopoJSON. Asynchronous data fetching is handled via custom hooks using D3’s `csv` and `json` loaders.

Fork of Points on a Map

This example shows a world map with graticules and country boundaries, overlaid with small circles representing cities with populations over 50,000. The map uses the `geoNaturalEarth1` projection and `d3.geoPath` to render land, sphere, and graticule paths from TopoJSON data. City positions are projected from latitude and longitude coordinates, and each city is drawn as an SVG circle with opacity. The visualization is built with React and D3 v5, loading data from a CSV of world cities and the World Atlas TopoJSON.

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.
