This example visualizes Relatedness Density across Swiss NUTS2 regions using a choropleth map. It employs the eurostat-map library to render the geographic boundaries as SVG, with a sequential color scale created via d3.scaleSequential and d3.interpolateYlGnBu to encode data values. The map uses threshold-based classification with specific cutoffs, and includes a legend and tooltips. The visualization also provides a button to download the rendered SVG, and adapts its layout and legend position based on viewport width.
