Colorimetry plot (CIE - xy ref)

Hi,

I am discovering plotly via dash for implementation on a website and am quite pleased for what I have found so far.
However I had a question. As I intend to use plotly for colour analysis, I wanted to plot my result on a xy colorimetry plot (https://en.wikipedia.org/wiki/Rec._2020#/media/File:CIExy1931_Rec_2020.svg) It basically has this rain bow colours in the background.
Is it possible to plot such a graph on plotly? Is it implemented?
The only solution I have found for now if using a background image to setup in the layout which is no ideal.

Thanks
