This visualization aggregates event sequences from network flow data, showing compact event sequence strips in the center alongside histograms of destination IP, port, and source IP attributes on the left. Users can filter events by typing a regular expression, which highlights matching sequence elements and updates a percentage counter. Selecting a sequence displays its event details, including name, content name, and content type, on the right. The implementation uses d3.hierarchy, d3.scaleBand, d3.scaleLinear, d3.axisBottom, d3.axisLeft, and SVG rendering with tooltips.
