This visualization displays solar energy data points as a scatter plot overlaid on a map of Indiana’s counties. Each circle’s radius encodes the `watt_max` value using a square-root scale, with the state boundaries rendered in black and county interiors in gray. The map is created with `d3.geoPath` and a custom Albers projection, while the data is loaded via `d3.csv` from a GitHub repository. The visualization uses React for component management, with D3 v5 handling the geographic projections and scaling.
