This choropleth map visualizes 2024 average household income estimates for U.S. states, using a blue-to-green sequential color scale to represent values from $50,000 to $100,000. The visualization uses d3.geoPath with a geoAlbersUsa projection to render TopoJSON state boundaries, with each state filled based on its associated income data. Interactive tooltips appear via mouseover events, showing the state name and income value, while a gradient legend with a d3.axisBottom scale displays the color-to-value mapping. The code leverages d3.scaleSequential, topojson.feature, and the us-atlas states-10m dataset.
