A Combination is always the best trick on Unix.

du -sk $(find . -type d) | sort -n -k 1

Will show directory sizes in KB and sort to give the largest at the end.
Tree-view will however needs some more fu... is it really required?

Note that this scan is nested across directories so it will count sub-directories again for the higher directories and the base directory . will show up at the end as the total utilization sum.

You can however use a depth control on the find to search at a specific depth.
And, get a lot more involved with your scanning actually... depending on what you want. Depth control of find with -maxdepth and -mindepth can restrict to a specific sub-directory depth.
