This example presents a choropleth-style map of Sweden’s counties, rendered as SVG paths with dark blue fills and gold interior borders. The visualization uses React to manage state and D3 v5’s `geoMercator` projection with `geoPath` and `fitExtent` to scale and center the map. County boundaries and interior borders are derived from a TopoJSON file using `topojson.feature` and `topojson.mesh`. The code includes a commented-out `geoEqualEarth` alternative and a video link, though the active map focuses solely on geographic outlines without additional data encoding.

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.

Sweden Map

This example presents a choropleth-style map of Sweden’s counties, rendered as SVG paths using the Mercator projection via `d3.geoMercator` and `d3.geoPath`. The map outlines each county with a red stroke and aqua fill, while internal borders are highlighted in teal. County geometries are loaded from a TopoJSON file, converted to GeoJSON using `topojson.feature` for areas and `topojson.mesh` for boundaries. The React component fetches and uses the data through `useData`, producing a static, interactive-free visualization.

Sweden map

This example visualizes the counties of Sweden as a choropleth map, using a red fill for each county and yellow lines to highlight interior borders. The map is rendered as an SVG using React, with geographic data from a remote TopoJSON file. The code employs `topojson.feature` and `topojson.mesh` to extract county boundaries and interior edges, and `d3.geoPath` with the Mercator projection to project the geometries. The projection is fitted to the map's extent using `fitExtent`.

Sweden

This example displays a choropleth of Sweden’s counties, rendered as a static SVG map without interactivity. Using React and D3 v5, it loads TopoJSON county boundaries via `d3.json` and converts them with `topojson.feature`. A Mercator projection (`d3.geoMercator`) and `d3.geoPath` draw the filled paths, with a fixed zoom scale and map dimensions. The code’s styling applies a teal fill and transparent stroke to each county.

Swedish map

A choropleth map of Swedish counties rendered as SVG paths, colored in a dark red with light gray borders. The map uses a Mercator projection fitted to the county boundaries, with internal borders highlighted in purple. The visualization is built with React using d3.geoPath for projection and path generation, and topojson’s feature and mesh functions to extract county polygons and interior boundaries from a TopoJSON dataset. The code includes commented-out options for an equal-earth projection and for scaling/centering the map, but the active projection uses d3.geoMercator.

SwedisH MAP

This example displays a choropleth-style map of Swedish counties, rendered as SVG paths with cyan fills and green boundary lines between regions. The visualization uses a React component structure with D3’s `geoMercator` projection and `geoPath` to draw geographic features from TopoJSON data. The map is loaded via the `json` method and processed with `feature` and `mesh` from the TopoJSON library, with the projection fitted to the viewport using `fitExtent`.

Swedish map

This example displays a choropleth map of Swedish counties, with each region filled in teal and interior boundaries highlighted in a contrasting color. It visualizes the geographic subdivisions of Sweden using geospatial data. The map is rendered as SVG with React, using the `geoMercator` projection and `geoPath` from D3 v5, and the TopoJSON data is converted to GeoJSON using the `feature` and `mesh` functions. The projection is fitted to the viewport via `fitExtent`. The data originates from a preprocessed TopoJSON file of simplified Swedish county boundaries.

Sweden map

This visualization displays a map of Sweden’s counties, with each region filled in brown and internal borders highlighted in black. It is built with React and D3 v5, using `d3.geoMercator` projection and `d3.geoPath` to render the TopoJSON data from the World Atlas. The example demonstrates how to load geographic data with `d3.json`, process it via `topojson.feature` and `topojson.mesh`, and apply custom styling through SVG paths.

VarshaGSweden

This example displays a choropleth-style map of Sweden’s counties, highlighting internal boundaries in cyan and county fill in dark blue on a light background. Using React with D3 v5, it loads TopoJSON data from a GitHub gist, converts it to GeoJSON with `topojson.feature`, and renders paths via `d3.geoPath` with a Mercator projection fitted to the viewport. Interior mesh lines are drawn separately using `topojson.mesh`. The visualization updates reactively when data loads.
