This stacked bar chart displays the counts of correct and incorrect responses, categorized by strong and weak confidence levels, across five timestamps from November 19, 2021. The chart uses d3.stack with stackOrderAscending to layer the four color-coded categories, while React checkboxes allow users to toggle which categories appear. The visualization is rendered as an SVG using d3.scaleBand and d3.scaleLinear for axes, with a useResizeObserver hook making the chart responsive to container width changes.
