A stacked bar chart displays the daily time allocation for five people across categories like work, exercise, and leisure, with each bar segmented by activity and scaled from 0 to 24 hours. The chart uses D3 v7’s `d3.stack` to compute the stacked series, `d3.scaleOrdinal` for color encoding, and `d3.axisBottom` and `d3.axisLeft` for axes. SVG rectangles render the segments, with mouseover effects and a tooltip, while the data comes from an inline CSV file with genres as rows and activities as columns.
