[FEATURE] Emit warning when data too large to render as image about bokeh

[bryevdv]

Consider emitting a warning when dataset is too large to plot.

Do you mean in Python? How could we know ahead of time? I expect this limitation is depends on browser version, OS, and possibly other issues. E.g. all of the above render fine on Safari for me:

Are there any console errors in your browser? I expect JS console message is the best we can do here.

ah, interesting. I didn't expect that. It works in Safari for me as well but not Chrome. I don't see any errors in the Chrome console. I think a message there would be sufficient.

It really depends on the browser and its config. Additionally browsers can either reach these limits silently like Chromium does or fail hard like Firefox does, e.g.:

and at a much lower threshold than Chromium.

I will mark this as a discussion for the time being, but I strongly doubt we can do anything in general here.

sounds good. thanks for investigating! Maybe a note in the documentation would be a sufficient step for the short term.
