So if you looked at this in a jupyter notebook with a running server there would be the plot above with working dropdown menus. But otherwise nope.

In [49]:
holoviews.save(plot, "diseases.html")
In [51]:
renderer = holoviews.renderer("bokeh")
figure = renderer.get_plot(plot).state
javascript, tag = autoload_static(figure, CDN, "diseases.js")
In [52]:
print(tag)

<script src="diseases.js" id="5e346ec9-db34-4143-bfa3-a2fe8d2e0da0"></script>

In [56]:
with open("../../files/posts/libraries/holoviews-tabular-data-take-two/diseases.js", "w") as writer:
    writer.write(javascript)

Okay, so weirdly, using autoload_static seems to be what's breaking it, because even the javascript exported by this notebook doesn't have the dropdown menu.
