This dashboard presents four coordinated views of San Francisco hate crime data from the SFPD, showing victim counts by suspect race and bias type, suspect counts by race and offense, and a monthly victim timeline. The bar chart uses `d3.rollups` for aggregation, the treemap employs `d3.treemap` with `d3.hierarchy`, and the bubble chart positions nodes via `d3.forceSimulation` with collision detection. An animated area chart uses a line path with dashoffset transitions and hover tooltips across all views.
