BC Offsite Species
This visualization displays British Columbia offsite species data on a world map, with bubble size reflecting area in square kilometers. Users can brush the time-series histogram below to filter the mapped points. The map uses d3.geoPath with Albers projection and country boundaries from the World Atlas TopoJSON. The histogram bins data by month using d3.histogram and d3.scaleTime, with brushX interactions syncing the view.
