Once upon a fork, there was a notebook for visualizing Twitter data just for a very specific account.
The story continues, looks like you can now use notebooks to (get and) visualize Twitter data of every account out there.
Have data fun!
Saw your notebook in this youtube video that explained D3 in 100 seconds. 
Oh wow, cool! Thank you Brett for the pointer
