Understanding the complex behavior of magnetically confined fusion plasmas is an important goal of DOE's many fusion projects. The fusion community uses many different simulations to model the effects of physical and electromagnetic phenomena that contribute to plasma stability and effective plasma containment. These phenomena include radio frequency heating, stellerator and tokamak geometries, magnetic field evolution, and eddy stability. The fusion community has made an investment in visualization capabilities resulting in capabilities for producing compelling imagery. Despite that investment and prior work, our stakeholders have clearly stated they need visualization tools that provide the ability to test hypotheses in a visual environment, and that can process the large data being produced now and in the future on DOE's large open computing facilities. As one notable fusion scientist at ORNL put it, "If we knew what we were looking for, we'd just go make a picture of it."
