This example displays an interactive choropleth map of Slovakia’s districts, highlighting each district’s name on hover. The map is rendered using SVG with D3 v5’s `geoMercator` projection and `geoPath`, while `topojson.feature` converts district boundaries from a TopoJSON file. District labels are linked via a TSV file, and zooming is enabled through D3’s `zoom` behavior. The page also includes a separate car-report demo that uses Promises and ES6 modules.
