This change adds a new button that switches between the Map View and the Histogram View.

The top part of the Map View looks like this:

The top part of the Histogram View looks like this:

I found it a little surprising how the whole screen switched around when clicking this button.
I'm wondering if there is a better location or perhaps a tab control to make it more obvious what clicking it does.

I agree the UX of switching the view has considerable room for improvement. But I would caution us to keep in mind the context we're still in, namely that of putting together a sufficiently functional prototype, not (yet) that of actual product development.

Perhaps there's an easy enough way to improve the UX on this, but if not, I'd argue allowing a user to submit or specify their own dataset should be the higher order of priority in terms of getting ready for the Image Datapalooza.

LGTM. Just a suggestion for a better button name and some there are a few randomly left in commented out bits of code you may want to remove.

I definitely agree that the layout for that quadrant could use some improvement, and I set up an issue (#21) to brainstorm solutions. I also agree with @hlapp that functionality for Image Datapalooza needs to be prioritized.

BTW @egrace479 given that there've already been two pairs of eagle eyes, I'm not sure there's anything I can add, so please don't wait for my review or approval.
