graphical representation of `du`

[Ryan Coleman]

I found this command:
ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/   /' -e 's/-/|/' 

Which makes this:
   |-Mar17
   |---1300074369-chow
   |-----download
   |-------small
   |---1300421616-Cunningham
   |-----download
   |-------small

But I want to use `du` instead to convert this
2.0M	./Mar17/1300074369-chow/download/small
2.0M	./Mar17/1300074369-chow/download
2.0M	./Mar17/1300074369-chow
2.1M	./Mar17/1300421616-Cunningham/download/small
2.1M	./Mar17/1300421616-Cunningham/download
2.1M	./Mar17/1300421616-Cunningham
4.1M	./Mar17

into this:
   |-Mar17 [4.3M]
   |---1300074369-chow [2.0M]
   |-----download [2.0M]
   |-------small [2.0M]
   |---1300421616-Cunningham [2.1M]
   |-----download [2.1M]
   |-------small [2.1M]


I realize it does it backwards and I can live with that...  OR mix the two to run the first command and run another command to get the folders total size or something... you know?

Thanks for the help,
Ryan
