[Feature request] 2D Histograms in seaborn.objects interface

[berkgercek]

Heya,

Insofar as I'm aware, there is no way to use the existing objects in the new API to produce a 2D histogram.

I'd really like this functionality, particularly because I'd like to be able to use something like the seaborn.histplot function from the old API, but with the option of adding annotations to each bin so I can see the stat associated with the bin in 2D space.

Currently to accomplish the above I'd have to manually bin the data using e.g. np.histogram2d and then pass it to seaborn.heatmap for plotting with annot=True kwarg. While this is totally doable, I see the opportunity for the really elegant compositionality of the objects interface to shine with this.

Thanks for your time!

Yes, expect support for this in the future.

Just piping in to say that I'd also really love this feature. Using a scatter plot with alpha=0.2 isn't quite the same.
