I am trying to create a data visualization that allows a user to dive
deeper into the data. I thought a tree map would a good way for
someone to dive into my data. I have run into a little problem with
the tree map though. I have reoccurring data below each node, and the
only way I can make it appear is by making each variable unique. An
example of the problem is below
regionid parentid state.area state.area.log
1 USA <NA> 100.0 15.10154
2 Northeast USA 25.0 12.03974
3 South USA 25.0 13.70966
4 North Central USA 25.0 13.54832
5 West USA 25.0 14.39435
6 Banana Northeast 12.5 25.00000
7 Apple Northeast 12.5 25.00000
8 Banana South 12.5 25.00000
9 Apple South 12.5 25.00000
10 Banana North Central 12.5 25.00000
11 Apple North Central 12.5 25.00000
12 Banana West 8.0 16.00000
13 Apple West 8.0 16.00000
14 Strawberry West 9.0 18.00000
When I run this it puts all the Apple's and Banana's in the Northeast
and only leaves Strawberry in the West. I know i can fix the solution
by appending the region to the fruit (i.e. Apple-West) but this
solution isn't as clean as i would like in presentation. Any one have
a solution or suggest a new visualization?
