BioReact: Visualization of Systems Biology Network

It is often difficult to visualize large networks effectively. In BioReact, we filter large systems biology network data by querying to select partial network as the input for visualization. Each query is parameterized by a node name, the direction of graph search, and the scope of the search. We present two layouts of the same network to clearly show network topology: a force-directed layout expands neighbouring nodes to maiximize spatial separation between nodes and links, and a downward edge layout to preserve a sense of unidirectional flow. Navigation of the network such as locating a particular node/link and linked highlighting between multiple views optimize user experience.
