PIVOT

        PIVOT is a simple yet flexible visualization tool based on Circos, which offers a fast and aesthetic visualization of data and information. The Protein Interaction Visualization and Observation Tool (PIVOT) was developed specifically for the visualization of protein interaction. It is difficult to spot the proteins that have an interaction when given a large list of proteins but with PIVOT, it is easy to identify the them at a glance. PIVOT displays an image showing all the proteins and draws a connection between proteins that have an interaction.

        PIVOT is will be available for free under GPLv3 at SourceForge once the paper on it is reviewed.
