VI3 - James Eanes

Three things learned from these tutorials:

Understanding the animation tutorial was very difficult - it doesn't give you the source as you go (like the other D3 tutorial), it just embeds the examples in the larger source of the main page.
Combining two sections of code using
tags is completely beyond me. I will have to look more into this, but I have no idea how to do it at this point.
The use of a small set of commands to animate objects on the screen is very powerful and extemely useful...but I imagine could be very overdone and annoying to the user.
