This visualization shows the distribution of police shootings per year across racial categories, using box plots to display the minimum, first quartile, median, third quartile, and maximum for each group. The code groups the data by race, then calculates yearly counts and quantiles for each category. It uses React to render the SVG, with d3-scale functions such as `scaleBand` and `scaleLinear` for positioning, and `d3.quantile` for statistical summaries. Data comes from a CSV of police shooting incidents.
