Matplotlib also lends itself to easy tests of interactivity, e.g.:

Basically, you can mimic any mouse event and let the "Event Manager" parse it.

> Which got me thinking a bit. Someone (I forgot who) mentioned that the emails were likely being done in a GUI (and this one certainly is). But it's GUI used by millions of people, and has very substantial developer effort behind it. Arguably it's much simpler than what is needed for spectral analysis and visualization. So what widely used GUI data visualization/analysis applications (let's say non-web for the moment) in astronomy have stood the test of time? I.e., those used only by astronomers. Certainly DS9. (Perhaps imexamine and splot, though those are more like the simpler approach above rather than what we consider GUI's). Aladin? TOPCAT. There are a number of VO-related tools that are GUI's but I'm not sure how heavily they are used. What is people's views of these?

ds9 is the only astronomy GUI I used 8 years ago that I *willingly*
use now.  I'd definitely like to hear others' takes on this.  If we
want general community feedback, perhaps an astrobetter post asking
for community feedback about what they like/dislike about astronomy
GUIs would be appropriate?

I really hope the push @mdboom has been making to incorporate mpl &
the browser allow us to use a js frontend for all of our needs.
(both those links were already posted but they deserve even more attention)
