In short:

> Question: How can I "save" a static snapshot...?

You can't yet.

Question: If so, can I then ...recreate the pie chart?

No, not yet.

Overall, these are features that we definitely want and we are working
towards them. Questions remain for me, if I understand your original
questions, about these two features.

Re: saving a visualization to a history:

   - What is the final use of the 'hardcopy' (png or pdf) of the
   visualization? In other words, is it for: publication or exposition,
   summary/overview info, a jumping off point for exploring the data, or
   something else?
   - Isn't this an artifact (a view or byproduct) of the analysis and not
   actually a dataset itself?
   - Do you want a static version or, if possible, easier access to a
   pre-configured interactive visualization?
   - Would a saved visualization (of the type you find under
   'Visualizations->Saved Visualizations' menu) work in a png or pdf's place?

In any event, I think more flexible conversion of visualizations to
hardcopies is doable with some added backend technology like ImageMagick to
render SVG to PNG, etc. If also wrapped in a tool, this would let us add
these to the history.

Re: generating a visualization from a workflow:

   - Would a saved visualization work here as well?


I think the main problem here is translation of what may be a more complex
visualization UI (to control the configuration) to something that can be
more simply rendered in a workflow page (as tool configurations are now).
At least some of the configuration could be handled this way, at any rate -
things like Chart's chart type, and data columns, etc.

There are ways to pass visualization configurations directly over the url,
so this may be easier than I think too.

These are good ideas. Thanks, Peter.
