A choropleth-style map of Slovakia renders district boundaries as SVG paths, filled in light green with thin black strokes, on a white background. The visualization uses D3 v5’s `geoMercator` projection and `geoPath` to convert TopoJSON data from a local `okresy.json` file into geographic features. An auxiliary feature below the map displays a list of filtered car prices, generated asynchronously from a hardcoded dataset via a promise.
