This visualization presents global literacy rates through a static world map alongside a U.S. state-level map with simulated data values from 70 to 100. The U.S. map uses a soft blue gradient color scale via `d3.scaleSequential` and `d3.interpolateGnBu`, with hover tooltips showing state names and values. Rendered in SVG using `d3.geoPath` with `d3.geoMercator` and `d3.geoAlbersUsa` projections, it includes a legend built with `d3.axisBottom`. Geographic data comes from World Atlas and US Atlas TopoJSON sources, while state values are randomly auto-generated in the code.
