This example demonstrates interactive map rendering with D3.js, displaying world countries with hover effects that change their fill color and tooltips showing country names. The visualization loads geographic data from the world-atlas package, combining TopoJSON with TSV metadata to map country IDs to names. It implements a zoom feature using D3’s zoom event system, which applies transform attributes to the map container. The code also includes a car listing report that filters and formats data asynchronously from JSON, showcasing D3’s promise-based data loading and ES6 module integration.

This example shows a world map with countries rendered in light green against a dark blue sphere, drawn using D3’s `geoPath` and `geoNaturalEarth1` projection. Hovering a country turns it red, while a zoom interaction (via `zoom`) allows mouse-driven pan and scale. The map data comes from a TopoJSON file and a TSV file paired through `Promise.all`; the SVG output is generated by projecting geographic features, with tooltips provided by `title` elements.

This example demonstrates a zoomable world map with hover interactions, where countries change color on mouseover. It renders geographic features using d3.geoPath with a d3.geoNaturalEarth1 projection, and applies zoom behavior via d3.zoom to transform the map group. The map data comes from a TopoJSON file combined with a TSV file for country names, loaded through d3.json and d3.tsv. The SVG is styled with CSS for the country fills and hover effects.

This example shows an interactive world map that supports zooming and panning, with country names revealed on hover. It renders geographic data using D3’s `geoNaturalEarth1` projection and `geoPath` into SVG, with country boundaries from TopoJSON and names from a TSV file. The zoom behavior is implemented via `d3.zoom`, applying a transform to a group element. Hover effects increase stroke width via CSS, while `title` elements display each country’s name.

This example shows a world map with hover and zoom interactions. It renders country boundaries and names using a Natural Earth projection, with each country highlighted in red on mouseover. The visualization loads geographic data from the world-atlas TopoJSON dataset and joins it with country names from a TSV file. It uses d3.geoPath with d3.geoNaturalEarth1 to draw the map, d3.zoom to enable pan and zoom, and SVG title elements for tooltips.

This example shows a world map rendered with D3 v5, using Natural Earth projection and TopoJSON data. Users can pan and zoom the map via d3.zoom. Hovering over a country turns it red, with country names available as tooltips via SVG `<title>` elements. The code uses d3.geoNaturalEarth1, d3.geoPath, and d3.event for interactions.

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.

A world map rendered with D3's geoNaturalEarth1 projection presents countries in light green against a blue sphere. The visualization loads country boundaries from the world-atlas TopoJSON and TSV files, using d3.geoPath to generate SVG paths. Interaction is handled via D3's zoom function, which applies a scale and translate transform to the map group on zoom events, while a CSS :hover rule turns countries red when moused over.
