save svg

[mattiik]

Hi,

I would like to save a graph from holoviews (bokeh backend) to svg.
When using the example from here https://holoext.readthedocs.io/en/latest/examples/save_to_png_svg.html
I get the following error message:

`---------------------------------------------------------------------------

Hi @mattiik thank you for your interest, but holoext hasn't been updated for a while now due to its deprecation. If you'd like to save to SVG, see and bump holoviz/holoviews#2966
