Three linked D3.js views explore a dataset of US states: a scatterplot maps time of creation against score with circle size encoding comment count, a symbol map projects agricultural productivity onto an AlbersUSA geography, and a time-based brush chart displays event markers. Hovering highlights matching points across all views via dispatcher events, while brushing filters the scatterplot and map through the `brush` component’s `brushend` handler. SVG transitions animate updates, and the map uses TopoJSON for state boundaries.
