This visualization displays the number of police shootings recorded by racial category, using a bar chart where bar heights correspond to aggregated counts from a CSV dataset. The chart is rendered in SVG via D3.js v7, using `d3.csv` for data loading, `d3.rollup` for aggregation, and `d3.scaleBand` and `d3.scaleLinear` for positioning. CSS hover effects change bars from steelblue to orange, while axis labels are added via `d3.axisBottom` and `d3.axisLeft`.
