Animated Radar Chart that adds lines instead of redrawing them per period

Hello,

I´d like to recreate a radar chart like the Global Mean Temperature Chart (top right) on this climate data site:

Using animation_frame = ‘Year’, in px.line_polar(), the figure draws only one line per year, but of course, the persistent lines in the Temperature Chart tell a story, while my version of rapidly flickering lines just create confusion.

Is anybody aware if persistent lines can be created without having to learn and do it in java script? :thinking:
