This visualization shows a choropleth map of the United States, displaying the number of clean energy jobs per 1,000 workers. The map uses a green sequential color scale with threshold breaks, allowing viewers to compare state-level employment data at a glance. The visualization is built with d3.v7, using `d3.geoAlbersUsa()` for projection and `d3.geoPath()` to render state boundaries. It loads data from a CSV file via `d3.csv` and U.S. state boundaries from the us-atlas TopoJSON, while `d3.scaleThreshold()` assigns colors based on job density values. Hovering over a state reveals a tooltip with its specific data.
