A bar chart displays the relative proportions of work, stop, and idle time for four crews, using horizontal stacked bars. Each crew’s row is composed of three colored segments whose lengths correspond to the numeric values from the CSV data. The visualization uses D3 v5’s `csv`, `scaleLinear`, `scaleBand`, `scaleOrdinal`, `axisLeft`, and `axisBottom` to load the data, position the bars, and render axes in SVG. A static color scale assigns distinct hues to the three activity categories.
