[Feature Request] Heatmaps in polar coordinates

[curldivergence]

Hi! Is there any chance it's currently possible to create a polar-coordinates heatmap using plotters?

Unfortunately didn't see anything like it in the examples.

Thank you!

Hi there, thanks for using plotters.
Unfortunately, plotters doesn't support polar axis currently - it's on the to do list.

Recently, a PR was merged for pie plot which is related to the polar coordinate - however, in currently version this is not yet supported.

See https://github.com/plotters-rs/plotters/blob/master/examples/pie.rs for the details about the pie plot.

And we are definitely want to add this feature to the next release.

Cheers!
Hao
