This example displays a parallel coordinates plot of subsea control module quality notifications. It shows how multiple categorical attributes—including notification origin, priority, type, and various defect descriptors—relate across dozens of recorded issues. The visualization uses D3 v3’s `d3.svg.axis`, ordinal and linear scales, and a line generator to render each data record as a polyline. Data is loaded from a pipe-delimited text file via `d3.dsv` and rendered as SVG with interactive brushable axes.
