The visualization displays 51 logged user traces as vertical bars, where each bar’s height encodes the trace duration in minutes and its horizontal position corresponds to the trace’s start time. Colored background rectangles group traces by their activity sequence, distinguishing conforming from non-conforming patterns. The chart is built with D3 v5, using `scaleTime`, `scaleLinear`, and `scaleOrdinal` for axes and coloring, while SVG `rect` elements handle rendering. Clicking a bar reveals a popup detailing the trace number, start and end times, and total duration.
