a minimal resizable container for the container size problem

[oheil]

This is an experimental proposal for this issue:
#253

It produces a resizable div container for every plot and fires a window resized event if the div size has changed. It is using minimal JavaScript and works in latest Firefox and Chrome, not in Edge.

How do you like it?

I have to admit that I still hope that might be solvable in the vega/vega-lite code without us going through so many hoops. If not, then I guess we'll have to go with something like this... I do think it would have to work on all browsers though, including Edge...

Yes, I fully concur.
The current situation is:

1. div container with undefined size
   • VegaLite size option "container" does not work
2. setting a single div container size to 100%
   • VegaLite Editor Menu missplaced, outside of visible area
3. resizable div container
   • additional special JavaScript code (complex, browser compatibility)
   • visibility of the resize widget (lower right corner) bad
   • initial size of the container may not be appropriate (e.g. if plot is small)
