This paper presents an approach to exploring multidimensional data cubes with hierarchical visualization techniques. Analysts interact with data in a predominantly "drill-down" fashion, i.e. from coarse grained aggregates towards the desired level of detail.

We introduce a class of visual structures called Enhanced Decomposition Tree. Every… CONTINUE READING
