Forked from Polished World Map

This example displays a world map with country boundaries, graticules, and city points sized by population. The map uses D3’s `geoNaturalEarth1` projection with `geoPath` to render land, interiors, and sphere outlines from World Atlas TopoJSON data. City coordinates from a CSV are projected onto the map, with circles scaled via `scaleSqrt` based on population. The visualization is built with React, rendering SVG elements, and uses D3 v5 for data loading and geo utilities. Styling is applied through CSS to differentiate land, graticules, and interiors.

Points on a Map

This example displays a world map with city points sized by population. The visualization uses the `geoNaturalEarth1` projection and `geoPath` from D3 to render landmasses, graticules, and interiors from TopoJSON data. City coordinates are projected onto the map, and their radii are scaled with `scaleSqrt`. The entire visualization is built with React and uses D3’s `csv` loader to bring in city data from a remote CSV file.

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 a Map

A world map displays country boundaries and graticules over a light gray sphere, with semi-transparent teal circles sized by city population. The visualization uses d3.geoNaturalEarth1 for projection and d3.geoPath to render land, interiors, and sphere outlines from TopoJSON data. City coordinates are projected and drawn as SVG circles, with radii scaled using d3.scaleSqrt applied to population values from a CSV dataset. The React component structure manages state for both world atlas and city data.

Points on a map

This example displays a world map with points representing cities, sized by population. The map is rendered as SVG using React, with D3's `geoNaturalEarth1` projection and `geoPath` drawing landmasses, graticules, and sphere outlines. City coordinates are projected onto the map, and circles are scaled with `scaleSqrt`. The code loads world topology from a JSON via `useWorldAtlas` and city data from a CSV using the `csv` utility, styling land areas and points with CSS.

Points on a map

This example displays a world map with city points scaled by population using a square-root scale. The map is rendered with D3’s `geoNaturalEarth1` projection and `geoPath`, showing land masses, interiors, graticule, and sphere outlines. City circles are positioned via the projection and styled with opacity, while the component structure uses React with custom hooks to load TopoJSON world data and CSV city data. The visualization clearly communicates population distribution across the globe.

Points on a Map

A world map displays the geographic distribution of cities, with circles sized by population. The visualization uses a natural Earth projection with graticules, land masses, and country borders. Built with React and D3 v6, it employs `geoNaturalEarth1`, `geoPath`, and `geoGraticule` to render the SVG. City data comes from a CSV of world cities, while country boundaries derive from World Atlas TopoJSON. Circle radii are scaled using `scaleSqrt` based on population values.

Points on Map

This example displays a world map with city points overlaid, using a Natural Earth projection. The map shows country boundaries, graticules, and a sphere outline, with city locations plotted as circles. It uses d3.geoNaturalEarth1, d3.geoPath, and d3.geoGraticule to render the geographic features, while city data is loaded from a CSV via d3.csv. The visualization is built with React, rendering SVG elements, and uses TopoJSON from the World Atlas for country polygons and interior borders.

Points on a Map

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.
