This bar chart displays Brazilian public budget expenditures, comparing committed (“Empenhados”) and paid (“Pagos”) values by year. Users can filter the data by fiscal category (“Resultado Primário”) and government function (“Função”) via dropdown menus. The visualization uses D3 v5 with `d3.csv` for data loading, `d3.nest()` for aggregation, and `scaleLinear` and `scaleBand` for axes. Bars are rendered as SVG rectangles, with tooltips on hover and axis labels customized using `axisBottom` and `axisLeft`. Data originates from the provided `orcamentoData.csv` file.
