An example of an SVG interaction layer over a canvas rendering layer. Data from the USDA Nutrition Database.

This example has a few design differences from most parallel coordinates:

requestAnimationFrame for gradual rendering
shuffled rendering order (Fisher-Yates)
bezier curves with canvas
autoscaling opacity
tick toggles
dark/light themes

D3’s default path interpolation is the same as its string interpolation: it finds numbers embedded in strings, and interpolates those numbers. So, the default behavior when interpolating two paths is like this:

M x0, y0 L x1, y1 L x2, y2 L x3, y3 
   ↓   ↓    ↓   ↓    ↓   ↓    ↓   ↓
M x0, y1 L x1, y2 L x2, y3 L x3, y4

For example, the first point ⟨x0,y0⟩ is interpolated to ⟨x0,y1⟩. Since x0 is the same, all you see are the y-values changing (see example)—you don't see the path slide to the left as intended.

What you want to happen here is something like this:
