Treemap .... such a big lie ...

Here I will talk about the real nature of treemaps and the unfortunate fact of their pleasent appearance dispite their misleadng reality ...

I will use this post to present my version of a more reliable hierarchical representation that uses the same compact technique as a treemap: treestack

What is a treemap?


A treemap is just a hierarchical partition of a usually rectangular space in which every rectangular part represents quantitative properties through visual charactetistics like area and color.

LEP - A kingdom of data

- Do you think is possible to ever think about database design again?

- Do you think is possible to center the analysis and design of databases around a unique and universal design?

- Do you think is possible that dispite universality we can keep good performance?

- Do you think is possible to represent ANY information system using only one database design, so we can concentrate the attention on functionality and NOT on structure?

These are the questions I will try to answer in this post and even give an example of a real application.

I won't give detailed mathematical demonstrations ... it would be boring ... but you won't be disapointed either....

I am the center of the universe ... and so are you ...
