I discovered how to use Bokeh in Holoviews without needing that
geckodriver. If you write the actual interactive output - instead of a png
file - you don't even need a renderer. You can just embed the interactive
html output directly.
Here is the revised code for RsT rendering in VR3:
@language python
import holoviews as hv
hv.extension('bokeh')
xs = range(-10,11)
ys = [100-el**2 for el in xs]
curve = hv.Curve((xs, ys))
hv.save(curve, 'curve.html', backend='bokeh')
@language rest
Here is the resulting interactive graph:
.. raw:: html
:file: curve.html
If you change the extension and backend to 'matplotlib', you get a static
graph instead of an interactive plot.
