This stacked bar chart visualizes how donation amounts are split between COVID-19 and other purposes across different giving categories. Users can toggle between total donations, COVID-only, and other-purpose views via an interactive menu. The visualization uses React with D3 v6, employing `scaleBand` for the y-axis and `scaleLinear` for the x-axis, rendering SVG rectangles with fixed heights. A striped pattern masks the first segment to distinguish it visually, while tooltips show percentage values. Data comes from an external CSV file about giving methods.
