This parallel coordinates chart visualizes 13 numeric petroleum price attributes across weekly dates from a CSV file, with each line representing a time series. The D3 v7 code renders SVG paths for all data points in blue, with axes scaled linearly per dimension. Interactive legend buttons allow filtering by dimension, highlighting lines in the top 10% of values for the selected attribute while dimming others. Tooltips display the week date on hover, and the line generator uses `d3.line()` with `d3.scalePoint()` for positioning.
