A choropleth map of Slovakia highlights its districts, which are colored light green and turn red on hover. The map uses a Mercator projection with `d3.geoPath` to render district boundaries from TopoJSON data, while district names are loaded from a TSV file. Zooming is supported via `d3.zoom`, and the visualization also demonstrates asynchronous data loading with `d3.json` and `d3.tsv`. A separate report lists filtered car data from a local JSON file, generated with `getCars` and `generateReport`.
