HumMod Browser: An Exploratory Visualization Tool for Model Validation of Whole-Body Physiology Simulation

We present HumMod Browser, a multi-scale exploratory visualization tool that lets physiologists validate human physiology simulation results. Showing correlations, exploring causality relationships, analyzing important attributes, and comparing numerous set of ensemble runs are common tasks in model validation. The lack of interactive exploration often hinders efforts to employ classical graph-visualization approaches in these tasks. Our HumMod Browser contributes to the interaction design and provides powerful multi-scale coordinated uncluttered interactive exploration based on tag-cloud visualization and a metaphorical interface. Two case studies containing more than 6000 physiology attributes suggest the usefulness of HumMod Browser in physiological simulation validation tasks.
