A grouped bar chart compares annual totals for Hail, Tornadoes, and Winds across four damage categories: property loss, crop loss, injuries, and fatalities. It aggregates CSV data from three separate Google Drive sources, summing each metric per event type. The visualization uses D3.js version 6’s `scaleBand` for the categorical axes and `scaleLinear` for the value axis, rendering four distinct colored bars per group via SVG rectangles. An ordinal color scale maps each category, with legends and axis labels generated using `d3.axisBottom` and `d3.axisLeft`.
