A bar chart displays total global videogame sales per year, filtered by selected publishers from the dataset. Users can select one or multiple publishers via a React dropdown menu, and the chart updates to show aggregated sales for those selections. The visualization uses Vega-Lite API with d3.csv to load the videogames sales dataset and renders the chart as SVG. React manages the interactive state, while Vega-Lite's transform for grouping by year and summing global sales powers the aggregation.
