This bar chart displays the distribution of work, stop, and idle time for four different crews, with each crew represented by a horizontal bar. The chart uses a time-based x-axis and a categorical y-axis, with green bars showing the population value from the CSV data. The visualization is built with D3.js, using scaleTime for the time axis, scaleBand for positioning the bars, and scaleOrdinal for color mapping, though the bars appear uniformly green due to CSS styling. Data is loaded from a CSV file and rendered as SVG.
