This example demonstrates a world map with zoom and hover interactions. Using D3’s `geoNaturalEarth1` projection and `geoPath`, it renders country boundaries from TopoJSON world-atlas data, with country names loaded via TSV. A D3 zoom behavior on the SVG applies a transform to the map group, enabling pan and scale. Hovering over a country changes its fill to red via CSS, highlighting the selected region.

This example demonstrates a zoomable world map with country outlines and hover highlighting, rendered as SVG. The map uses D3's `geoNaturalEarth1` projection and `geoPath` to draw country shapes from the world-atlas TopoJSON dataset, with a sphere background. Interactive zoom is implemented via D3's `zoom` module, which applies a transform to the map group on zoom events. Country names are joined from TSV data, and hovering over a country fills it red via CSS `.country:hover`. The visualization is built with React and D3 v5.

This example demonstrates a zoomable world map rendered with SVG paths using D3.js. It shows country boundaries from the world-atlas TopoJSON dataset, with each country labeled by name via a title tooltip on hover. The visualization uses a natural Earth projection and implements pan-and-zoom interaction through d3.zoom, which applies a transform to the map group. Countries are colored light green and highlight red on hover, while the sphere background is dark blue. The code fetches both TopoJSON geometry and TSV country names concurrently with Promise.all.

This example shows a world map rendered with D3 v5 using the `geoNaturalEarth1` projection and `geoPath` to draw country boundaries from TopoJSON data. The visualization highlights how simple CSS hover effects can create interactivity, with countries turning red on mouseover. Pan and zoom interaction is implemented via `d3.zoom`, which applies a transform to the map group. The map uses data from the World Atlas TopoJSON and TSV files, with country names added as tooltips through SVG `title` elements.

This example demonstrates interactive pan and zoom on a natural Earth projection map. The visualization renders country boundaries from TopoJSON world-atlas data using `d3.geoNaturalEarth1` and `d3.geoPath`, with hover highlighting via CSS. The code applies `d3.zoom` to the SVG container, updating a transform attribute on a group element during zoom events. Country names from the `world/50m.tsv` file appear as tooltips using SVG `<title>` elements, while the sphere background and country fills come from external styles.

This example demonstrates interactive pan and zoom on a world map, with countries highlighted in red on hover and tooltips displaying country names via SVG `<title>` elements. It uses a natural Earth projection (`geoNaturalEarth1`) and renders geographic features with `d3.geoPath`. The map loads world-atlas TopoJSON data and merges it with TSV country names, while the zoom behavior is implemented through `d3.zoom` applied to an SVG group.

This example shows a zoomable world map with hover highlighting, using a natural Earth projection to render country boundaries from TopoJSON data. The map supports interactive pan and zoom through d3.zoom, with a tooltip title displaying each country’s name from a TSV lookup. Countries fill light green and turn red on hover via SVG styling. The visualization relies on d3.geoPath, d3.geoNaturalEarth1, and topojson.feature to draw geographic shapes.
