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.

A world map displays cities with populations over 50,000 as semi-transparent points. The visualization uses D3’s `geoNaturalEarth1` projection and `geoPath` to render landmasses, country interiors, and graticules from TopoJSON data. City coordinates are projected and drawn as SVG circles, with data loaded from a CSV via `d3.csv` in React hooks. The map prioritizes geographic context over point density, using a light gray palette for boundaries and teal circles for city locations.

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.

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 example displays a world map with cities whose populations exceed 50,000, plotted as semi-transparent circles. The map uses a Natural Earth projection via `d3.geoNaturalEarth1`, with landmasses, graticules, and country interiors drawn using `d3.geoPath` from the World Atlas TopoJSON dataset. City coordinates are projected from latitude and longitude into SVG circle positions, with the data loaded from a Simplemaps CSV via `d3.csv`. The rendering is handled in React, producing a clean, styled SVG visualization.

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.

A world map displays the locations of cities with populations over 50,000 as small semi-transparent dots, overlaid on landmasses with country borders and graticules. Using React, the visualization loads GeoJSON world-atlas topology and city data via D3’s `json` and `csv` methods, then projects coordinates with `geoNaturalEarth1` and renders SVG paths and circles through `geoPath`. The map’s gray land, interiors, and sphere are styled distinctly, while city points use D3’s `projection` to convert longitude and latitude into screen positions.

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.
