This grouped bar chart compares three severe weather types—hail, tornadoes, and winds—by aggregating four damage metrics: property damage, crop loss, injuries, and fatalities. The data loads from three separate Google Drive CSV files and sums each metric per weather category. Built with d3.v7, it uses nested band scales (x0 for categories, x1 for sub-bars) and a linear y-scale, rendering SVG rectangles colored via `d3.schemeCategory10`. Axes are generated with `d3.axisBottom` and `d3.axisLeft`, with a responsive margin-based layout.
