Respectfully, these animations are more gratuitous than beautiful. Animations are meant to add to the information and demonstrate relationships over time and place.

For the Simple bar charts, the animations should only show growth and decay, not fly around the screen nor flash through 16 decimal points of precision if the final value only needs 3.

The Pie Chart handles growth / decay very well, but it's only half-complete by starting with visible text markers around a pie that's not there.

Alphabet and State Bar Chart are simply bad, but I did enjoy the States Circle Pack animations. Curiously, I found the Circle Pack can't really display more than a dozen states at a time (at that size), and showing fewer is equally incomplete. So does it actually need a count slider?

Finally, the duration slider in the State Circle Pack doesn't add much to the information since all animations are slowed down, including fade out / in. It might work better if it simply paused on the informative steps (all old states, remaining states, all new states).
