A choropleth map displays county-level STAAR standardized test performance percentages across Texas, with orange-to-red shading representing score ranges and gray indicating missing data. The visualization uses d3.geoMercator projection and d3.geoPath to render Texas counties from a TopoJSON atlas, filtered by FIPS codes starting with 48. Unemployment data from a Plotly GitHub CSV serves as proxy test scores, loaded via Promise.all with d3.json and d3.csv. Interactive tooltips appear on mouseover, while a gradient legend with a linear scale communicates the color mapping.
