Reaction:Tree-Maps: a space-filling approach to the visualization of hierarchical information structures

This paper the author tells us how to visualize hierarchical structures.The paper presents an example of the OS directory tree structure. This is a very god example used I feel personally, as it is something we use daily.

As known the venn diagram approach has its own problems. Using the treemaps there is complete space utilization.However the one shortcoming that I saw is the inconsistencies on the horizontal and vertical axis.It is handled in a very complicated way which may give rise to problems.

On a whole I feel there are more solutions to be explored which the author hasn't deal with.
