This visualization displays the daily hours spent by five people across five activity categories—work, exercise, socializing, chores, and leisure—as a stacked horizontal bar chart. The chart uses a linear x-axis for hours (0–24) and a categorical y-axis for each person, with interactive tooltips showing percentage values on hover. The example employs D3 v7’s `d3.stack` for data stacking, `d3.scaleBand` for the categorical axis, `d3.scaleOrdinal` for category colors, and SVG rendering with custom CSS for styling.
