This map shows the population of cities worldwide as scaled symbols overlaid on a geographic projection. Using React with D3 v6, it renders a Natural Earth projection with graticules and land boundaries via `geoNaturalEarth1` and `geoPath`. City populations are encoded as circle radii using a square root scale (`scaleSqrt`) ranging up to 15 pixels, with the data sourced from a cleaned world cities CSV file. The visualization demonstrates a hybrid React-D3 approach, where D3 handles the mathematical projection and scaling while React manages the SVG markup and component lifecycle.

Sized Points on a Map

This example displays a natural Earth projection world map with cities rendered as semi-transparent points, where point size encodes population using a square root scale. The visualization layers graticules, land masses, and country borders using `geoPath` and `geoGraticule` from D3 v5, while React manages the component state and SVG rendering. City data is loaded from a CSV file with population values, and the map uses geographic coordinates projected through `geoNaturalEarth1`. The visualization demonstrates how to combine D3’s geographic and scaling utilities within a React-based SVG scene.

Sized Points on a Map

This visualization shows a world map with cities colored by population, using sized points where larger circles represent more populous cities. The map displays graticules, sphere outlines, and country boundaries with interior borders for clarity. Built with React and D3 v5, it uses `geoNaturalEarth1` projection and `geoPath` for rendering the map, while a `scaleSqrt` function maps city populations to circle radii. City data comes from Simplemaps World Cities Database, with country boundaries from World Atlas TopoJSON, all rendered as SVG elements.

Sized Points on a Map

This visualization displays a world map with cities of populations exceeding 50,000, using sized points to represent population magnitude. Natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` render landmasses, graticules, and country interiors from TopoJSON data. Circles are positioned through projection of latitude and longitude coordinates, with radius determined by a square-root scale (`d3.scaleSqrt`) mapping population values to a maximum radius of 15 pixels. The React-based implementation loads city data from a CSV using `d3.csv` and renders all elements as SVG marks.

Sized Points on a Map

A world map displays cities with populations exceeding 50,000, with each city represented as a circle whose area encodes population using a square-root scale. The visualization uses d3’s geoNaturalEarth1 projection, geoPath, and geoGraticule to render country boundaries and graticules, while React manages the SVG scene. City coordinates and populations come from a Simplemaps World Cities CSV, and country boundaries derive from the World Atlas TopoJSON, styled with subtle gray fills and strokes.

Sized Points on a Map

This visualization displays global cities with populations over 50,000 as semi-transparent circles on a natural Earth projection. Circle radius encodes population magnitude using a square-root scale, making larger metropolitan areas visually prominent. The map renders country boundaries, graticules, and sphere outlines via d3.geoNaturalEarth1, d3.geoPath, and d3.geoGraticule, while React manages the SVG markup. City data originates from Simplemaps, loaded through d3.csv, and geographical boundaries come from World Atlas TopoJSON, processed with topojson.feature and topojson.mesh.

Points on a Map with Size

A world map displays city populations as semi-transparent circles, with point size encoding each city’s population value via a square-root scale. The visualization uses the Natural Earth projection via d3.geoNaturalEarth1 and renders graticules, land masses, and country interiors with d3.geoPath. City coordinates are projected from longitude and latitude, while the map geometry comes from World Atlas TopoJSON processed with topojson.feature and topojson.mesh. React components manage the SVG rendering, and the data is loaded asynchronously from a CSV of world cities using d3.csv.

Sized Points on a Map

This example visualizes global population distribution by rendering sized circles for cities with populations exceeding 50,000. The visualization uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to draw countries, graticules, and interiors from World Atlas TopoJSON data. City positions are projected from latitude and longitude coordinates, with circle radii scaled by population using `d3.scaleSqrt`. The React component fetches city data from a Simplemaps World Cities CSV.

Sized Points on a Map

This example displays a world map with city points sized by population. It uses a Natural Earth projection via D3's `geoNaturalEarth1` and `geoPath` to render landmasses, graticules, and country interiors. The map’s cities, sourced from a Simplemaps database, are drawn as SVG circles with radii scaled by the square root of population using D3’s `scaleSqrt`. The visualization is built with React and D3, with styles for the land, sphere, and graticules defined in CSS, and data loaded asynchronously from external files.
