Abstract

Networks have remained a challenge for information visualization designersbecause of the complex issues of node and link layout coupled with the rich set of tasksthat users present.This paper offers a strategy based on two principles:(1) layouts are based on user-defined semantic substrates, which are non-overlappingregions in which node placement is based on node attributes, (2) users interactivelyadjust sliders to control link visibility to limit clutter and thus ensure comprehensibilityof source and destination. Scalability is further facilitated by user control of which nodesare visible. We illustrate our semantic substrates approach as implemented in NVSS 1.0with legal precedent data for up to 1122 court cases in three regions with 7645 legalcitations.
