ABSTRACT
This paper extends previous work on focus+context visualizations
of tree-structured data, introducing an efficient, space-constrained,
multi-focal tree layout algorithm ("TreeBlock") and techniques at
both the system and interactive levels for dealing with scale. These
contributions are realized in a new version of the Degree-Of-Interest
