This visualization displays three horizontally stacked bar charts comparing fault-localization metrics for Java source code lines, using suspiciousness, recency, and line complexity as measured values. Each chart shares the same y-axis ordering by line ID, with the next two panels omitting the left labels to emphasize differences. Built with D3 v5, the code loads data from a CSV file and renders SVG rectangles using scaleLinear, scaleBand, axisLeft, and axisBottom functions, applying steelblue bars across three separate chart regions.
