Choropleth map of Slovakia II
This interactive choropleth map of Slovakia colors each district by its administrative region, with a legend for filtering districts by region and zooming and panning available via d3.zoom. Built with React and D3 v5, it renders SVG paths generated by d3.geoMercator and d3.geoPath from TopoJSON data loaded alongside district-level TSV statistics. The map uses d3.scaleOrdinal with a spectral color scheme, and hovering reveals district names via SVG title elements.
