This visualization displays boxplots for unemployment rates and education levels across US counties, with the top five counties by education listed below. Each boxplot shows quartiles, whiskers, outliers, and invisible data points for hover interactions using d3 scales and joins. Data comes from unemployment and education CSV files, merged by FIPS code. The visualization uses d3.axisBottom, scaleLinear, quantile calculations, and d3-rosetta’s StateProperty for managing hovered state and updating the highlighted county.
