Fork of Making a Bar Chart
This bar chart shows total committed Brazilian government expenses per year, aggregated from the CSV data by year using d3.nest and d3.rollup. The visualization uses a linear scale for the x-axis, a band scale for categorical year labels, and SVG rectangles. Axes are generated with d3.axisBottom and d3.axisLeft, with tick labels formatted using d3.format to abbreviate large numbers.
