This visualization displays trace data from a manufacturing process as a time-series chart. Black horizontal bars represent individual trace durations, while colored background rectangles indicate the trace’s activity sequence length, using red for longer sequences and blue for shorter ones. Clicking a bar reveals a popup with trace details. The chart uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft`, rendering SVG elements from a CSV file.
