World Map

World Map

A world map renders 50m TopoJSON country outlines with a sequential orange color scale, encoding each nation's `color1` value from a TSV file. The visualization uses `d3.geoPath` with a Natural Earth projection, `d3.scaleSequential` with `interpolateOranges`, and React to manage data loading and SVG rendering. Countries missing data appear magenta, while graticules and ocean-sphere paths provide geographic context.

World

This example displays a static world map of all countries using a natural Earth projection. The visualization fetches geographic data from the world-atlas TopoJSON dataset and renders each country as a violet SVG path with black strokes on a green background. The code employs d3.json to load the data, d3.geoNaturalEarth1 for the projection, and d3.geoPath to generate the SVG paths. The topojson.feature method extracts the country geometries from the TopoJSON structure before binding them to the SVG elements.

Map

This example visualizes world countries as a choropleth-style map, coloring each country green with white borders on a dark blue spherical backdrop. The map renders as SVG using D3.js with a Natural Earth projection via `d3.geoNaturalEarth1`, and country boundaries are generated through `d3.geoPath`. Geographic data loads from the world-atlas TopoJSON file (countries-110m.json), which is converted to GeoJSON using the `feature` function from the topojson library. Hovering a country changes its fill to red, and each country includes a title tooltip displaying its name.

World Map

This world map visualization renders country boundaries as green SVG paths on a blue background using the Natural Earth projection. The code fetches TopoJSON data from the world-atlas package and converts it to GeoJSON using `feature` from TopoJSON, then applies `geoNaturalEarth1` and `geoPath` from D3 v5 to generate the geographic shapes. The static map displays all countries without interactive features, relying on D3’s JSON loading and SVG selection methods to append each country path.

World Map

This world map uses a natural Earth projection to display country boundaries, with a dark blue ocean sphere and light green landmasses. Hovering over a country turns it red and reveals its name via a tooltip. The visualization supports zooming and panning through d3.zoom, with geographic paths rendered using d3.geoPath. It loads world country geometries from TopoJSON and country names from a TSV file, both sourced from the world-atlas package.

World Map

This world map displays country boundaries using the Natural Earth projection, with countries colored in a light teal and highlighted in red on hover. The visualization uses D3.js v5 and the topojson library to load and convert TopoJSON data from the world-atlas package. The map renders as SVG paths via D3's geoPath and geoNaturalEarth1 projection, while the zoom interaction is handled through D3’s zoom component. Country names are joined from a TSV file using ISO numeric codes, shown as tooltips.

World test

This visualization displays a world map with countries colored light green against a blue sphere, using natural Earth projection. Hovering over a country turns it red, and users can zoom and pan the map interactively. The code loads TopoJSON and TSV data from the world-atlas package, converting TopoJSON to GeoJSON via topojson.feature and rendering paths with d3.geoPath. Zoom behavior comes from d3.zoom, while country names are joined from the TSV file and shown as SVG title tooltips.

World map

This visualization displays a natural Earth projection world map, with countries rendered as colored SVG paths on a blue sphere. The map uses d3.geoNaturalEarth1 and d3.geoPath to project and draw geographic features, while d3.zoom enables pan and zoom interactions that transform the entire map group. Country boundaries come from the world-atlas TopoJSON dataset, and the rendering uses SVG paths with hover highlighting that changes the fill color.
