Update anatomy figure for 2.x style changes.

* Enable black edges on scatter markers. Also, use `plot` instead of
  `scatter` for @efiring.
* Move major and minor tick annotation to left side, where they're
  visible.
* Shift tick label and axis label annotations outward to match corrected
  handling of tick length.
* Don't disable legend frame, which is not very distracting any more.
* Don't set figure facecolor, which is already white by default now.
* Use AutoMinorLocator to avoid minor ticks overlaying major ticks,
  causing a small glitch due to antialiasing.

Fixes matplotlib#7113.
