Project: Visualizing Protein-Protein Interaction Datasets

2-hybrid analysis datasets show the level of interaction between protein pairs in cells. However, it is often difficult for biologists to make sense of the patterns and relationships contained in the raw data. We developed the Protein Interaction Browser, a tool to provide visualization and navigation capabilities in large 2-hybrid datasets. It uses the doughnut view, a new overview + detail visualization technique, to display the data, and it provides interaction techniques that facilitate navigation and path identification.
