A choropleth map of global health and economic indicators is paired with an interactive scatter plot of related country attributes. The map colors countries using a linear scale for urban population rate, while the scatter plot encodes continent by color and population by point radius. Built with React and D3 v6, the visualization uses `d3.geoEqualEarth` and `d3.geoPath` for map rendering, dynamic axes with linear/log scale toggles, and animated transitions via `transition.attr` for smooth updates.
