 ## Existing solutions
 The [`openair`](https://github.com/openair-project/openair/tree/master) package for R provides all these features, but is obviously in R and not Python. The topic of bivariate polar plots in Python also pops up occasionally, like [here](https://stackoverflow.com/questions/61940629/bivariate-polar-plots-in-python), [here](https://stackoverflow.com/questions/61702585/pollution-rose-plot-gridded), [here](https://stackoverflow.com/questions/9071084/how-to-create-a-polar-contour-plot), and [here](https://blog.rtwilson.com/producing-polar-contour-plots-with-matplotlib/). Lastly, there is the existing [`windrose`](https://github.com/python-windrose/windrose) library, but it lacks bivariate polar plots.
