Tufte is a brilliant information designer. His books are phenomenal & enlightening. He bridges the gap between information crunching for okay results to stellar art-sensibility mediated delivery of visuals that are immediately comprehensible.
I had a look at the code you supplied and the project it comes from.
Both are interesting!
But, overall, it doesn't add much we don't have without Tufte.
I think my point is Tufte is a genius of print media. Online pages I think are different. In particular, (1) TEXT-FLOW works a different way since it has NO fixity per se; (2) the mental models of "side-information" for the web work optimally only if central account is taken of FORM-FACTORS (e.g. screen size & orientation) dynamically.
Just some thoughts
