This interactive parallel coordinates plot uses the D3.js v3 library to visualize a dataset of car characteristics, including fuel economy, engine displacement, power, weight, and acceleration. The SVG rendering shows each car as a polyline crossing multiple vertical axes, with steelblue foreground lines for focus and grey lines for background context. Users can drag the axis labels to reorder the dimensions and use the built-in brush component on each axis to filter the displayed cars dynamically, updating the foreground paths in real time.
