This map of Amsterdam displays the locations of universities and colleges, shown as small yellow circles, layered over the city’s neighborhoods, which are colored by district. A tooltip appears on hover, and clicking a school highlights it while fading the others. The visualization uses D3 v5 with a Mercator projection (`d3.geoMercator`) and path generation (`d3.geoPath`) to render TopoJSON neighborhood boundaries. City data comes from a local JSON file, and interactions like zoom and tooltips are implemented with D3’s zoom and event handlers.

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.

Sized Points on a Map

This visualization presents a world map with semi-transparent circles representing cities, where point size encodes each city’s area value. The map uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to render landmasses, interior borders, and graticules. City positions are projected from latitude/longitude coordinates, with circle radii scaled using `d3.scaleSqrt`. The React component fetches world atlas TopoJSON and city data from a CSV URL, rendering SVG elements within a `Marks` component.

Sized Points on a map

This visualization displays global cities as sized points on a natural Earth projection map, with circle radii scaled proportionally to population using d3.scaleSqrt. The map renders landmasses, graticules, and country interiors as SVG paths generated via d3.geoPath, while city positions are projected from longitude and latitude coordinates. The React component loads world atlas TopoJSON and city CSV data asynchronously, then applies semi-transparent teal circles to highlight population distribution across continents.

D3 Map Nederland

This example displays an interactive map of Dutch municipalities, coloring each region in light blue with black outlines and highlighting areas in solid blue on hover. The visualization loads geographic data from a TopoJSON file and renders it as SVG paths using D3 v5 with a Mercator projection. It employs d3.json to fetch the data, d3.geoPath with geoMercator for drawing shapes, and includes d3-zoom.v2 for potential panning and scaling capabilities. The hover effect is implemented through CSS, and each municipality includes a tooltip showing its name and ID.

D3 Map Nederland

This visualization displays an interactive map of Dutch municipalities, allowing users to click any region to zoom in and highlight it in red. Hovering turns municipalities orange, and clicking the background resets the view. Built with D3 v6 and TopoJSON, it uses a Mercator projection via `d3.geoPath` and implements zoom/pan with `d3.zoom`, applying smooth transitions through `transition.attrTween`. Municipal boundary data comes from a remote TopoJSON file fetched at runtime, rendered as SVG paths with animated scaling.

Sized Points on a Map

This interactive world map displays populated places with over 50,000 residents as sized points, using an orthographic projection that rotates and zooms when users click on individual countries. Built with React and D3, the visualization loads city coordinates from Simplemaps and country boundaries from World Atlas TopoJSON. The code uses d3.geoOrthographic, d3.geoPath, and topojson.feature to render landmasses, graticules, and water, while click interactions trigger transition.attrTween animations that interpolate projection rotation and scale to center the selected country.

Sized Points on a Map

This visualization displays a world map with circles sized proportionally to city populations, using data from Simplemaps and country boundaries from World Atlas TopoJSON. The map is rendered with SVG and React, employing d3.geoNaturalEarth1 and d3.geoPath for geographic projections, while a d3.scaleSqrt maps population values to circle radii. The visualization includes graticules and land/interior boundaries, with semi-transparent teal circles marking cities with populations over 50,000.

D3 Map Nederland

This example displays a zoomable map of Dutch municipalities using SVG paths colored light blue with dark outlines. Hovering highlights each region in blue, and a title tooltip reveals the municipality name and ID. The visualization uses D3 v5 with `d3.json` to load TopoJSON data, `d3.geoMercator` for projection, `d3.geoPath` for rendering, and `d3-zoom` for interaction. Data comes from the cartomap GitHub-hosted `gemeente_2020.topojson` file.

Sized Points on a Map

This example displays a world map with circles sized proportionally to city populations, using data from the Simplemaps World Cities Database. The map renders geographic features with d3.geoNaturalEarth1, d3.geoPath, and d3.geoGraticule, while country boundaries load from World Atlas TopoJSON. City points are placed via projection coordinates and scaled with d3.scaleSqrt, all built within a React component using SVG. The visualization includes graticules and styled land, sphere, and interior paths for a polished cartographic look.
