make size of plots configurable

[DJCordhose]

It would be great to have the sizes of plots configurable on all platforms even as SVGs. Same of the plots come out quite tiny and hard to read by default.

Can we get away with a scale factor on entire SVG? I see lots of figsize specs for each node in tree (hardcoded). Not sure there's an easy way to change all matplotlib figsizes. And, do you mean in notebooks or when calling viz.view()? Where are they tiny? I've not seen that. Colab?

[DJCordhose]

Yes, in notebooks, e.g. on Colab, but also locally. Scaling factor would be great

Hmm...I'm not sure how to scale the svg. I think this kinda thing might work:

from IPython.display import HTML
style = "<style>svg{width:50% !important;height:50% !important;}</style>"
HTML(style)

Nope. doesn't work.

Ok, crap. I think I know what to do. PAINFUL @DJCordhose but anything for you :)

Boom, Jack! scale parameter, but only on dtreeviz()

dtreeviz(regr,
       X_train,
       y_train,
       target_name='price',  # this name will be displayed at the leaf node
       feature_names=boston.feature_names,
       scale=(.8,.8)
      )

This looks great, but nothing more than I expected :)

Did you already publish 0.8.1? still getting 0.8.0 when installing via pip

It seems it is not working with 2 parameters scale:
TypeError: can't multiply sequence by non-int of type 'float'

Hi. Are you using the latest version? You might try pip install -U dtreeviz just to make sure?
