option to remove invisible output from importing hvplot.pandas/xarray about hvplot HOT 2 OPEN

Hi @michaelaye, I agree, this isn't great.

I've asked if there's a way to hide these in VSCode (microsoft/vscode-jupyter#15303).

On a somewhat related note, I've actually been thinking that hvPlot should also display the little logo like HoloViews does. I'm not sure why logo=False was set originally, perhaps because hvPlot only supported the Bokeh backend. Now it supports Matplotlib and Plotly too it'd make more sense to add it. Making it more obvious also makes it less likely for users to delete it (which can cause various problems). @michaelaye would you be fine with hvPlot showing the logos on import and on hvplot.extension calls?

For reference:

• jupyterlab/jupyterlab#11888
• holoviz/holoviews#5154

from hvplot.

if it anyway creates a line of output, i guess it might as well just show what's actually going on, but a really quiet way of operating should be possible as well.
