This bar chart shows the distribution of work, stop, and idle time for four different crews, with time plotted on a time-based x-axis and crews on a categorical y-axis. It uses D3.js version 5.11's `scaleTime`, `scaleBand`, and `scaleOrdinal` to map the data, and `axisLeft` and `axisBottom` for rendering the axes. The chart is drawn as an SVG with a green fill for the bars, and the data is loaded from a CSV file via `csv`. The x-axis range is set from November 2016 to February 2017, with a custom tick format function.
