Project description

NVSS 1.0 (Network Visualization by Semantic Substrates) enables users to specify regions to place nodes, and then control over link visibility. (Left Figure) With all CITES boxes checked, there are 260 black Supreme to Supreme citations and 89 red Circuit to Supreme citations. Users can limit the links by source and target regions of interest. For example, in the left figure, links are limited to Supreme to Circuit and Circuit to Circuit links, where the single brown Supreme to Circuit citation is apparent and the 18 green Circuit to Circuit citations are mostly visible. (Right figure) Limiting the selected Circuit Court cases to the two in 1990-1991 generates a comprehensible display of the 18 red Supreme Court citations and the 2 green Circuit Court citations.
