This visualization presents a tri-panel view of fault localization data for 25 source code lines, showing suspiciousness, recency, and line complexity as horizontal bar charts. Each panel shares the same y-axis ordering by line ID, enabling cross-comparison of metrics. The charts are rendered as SVGs using D3 v5, with the third panel featuring a sort button that reorders bars by line complexity. The suspiciousness and recency panels use `d3.scaleLinear` for x-axes, while all panels employ `d3.scaleBand` for categorical y-axis spacing. Data originates from a CSV file containing Apache Commons source file references.
