Thomas Passin and I have been discussing his vr3 plugin in private. This is
a great plugin. Our conversation deserves to be public.
Here I am going to discuss what I think I know about vr3 and its
relationship with the holoviews <http://holoviews.org/>and bokeh
<https://docs.bokeh.org/en/latest/docs/user_guide.html>packages. I'll keep
this as short as possible.
*vr3: the big picture*
vr3 allows you to interleave python code with rst, such that *both* parts
are shown in the vr3 pane. This is a great feature. For example, given the
following in the body pane:
@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))
curve.opts(width=350, height=300)
hv.save(curve, 'curve.html')
@language rest
Here is the resulting interactive graph:
.. raw:: html
:file: curve.html
You will see something like the attached file in the vr3 pane.
I wonder, though, whether some of the rST code is necessary. Thomas,
wouldn't it be simpler (for users) for vr3 to support something like:
@language rst
Here is the resulting interactive graph:
@image curve.html
Just a thought...
*Holoview and bokeh*
Holoviews and bokeh are both important projects. It's reasonable to use
both.
For vr3, using holoviews might be the better starting point, as shown
above. However, I personally am more more interested in the bokeh client
server architecture as it relates to Jupyter. I'm not sure how this
architecture relates to vr3.
*Summary*
Thomas is vr3's author. I'll stay out of his way.
In effect, vr3 makes every Leo node act like a Jupyter notebook cell.
I will be investigating bokeh's client/server architecture, independently
of vr3.
Thomas, any comments or corrections will be appreciated.
Edward
