A choropleth map of Slovakia's districts colors each region light green, with hover states turning red, based on district-level housing statistics from a TSV dataset. The visualization uses D3 v5’s `geoMercator` projection and `geoPath` to render TopoJSON district boundaries, while `d3.zoom` enables interactive panning and zooming. A report listing cars under a price threshold appears below the map, generated asynchronously via promises.
