Remove extra padding in plots

@sroy3 I like this!

A few comments:

• top and right spacing does look even? (can be just an optical illusion?). Feels like the right one can be a bit bigger?
• how does it look like with grips?

It's equal, it's probably because of the label. It's all Vega spacing now since there is no more padding.

* how does it look like with grips?

I made sure to include the gripper when I took the screenshot, but I guess that didn't work. There is just enough space for it.

note: from the storybook, right edge on-hover numbers are cropped when plots is zoomed (I remember you explicitly fixed this for non-zoomed)
