Identifcation of important isovalues of scalar felds is a well studied problem. In this application we have used a relation-aware approach to explore scalar multifeld data. In the context of multifeld data, we calculate a variation density function, whose profle is a good indicator of interesting isovalues of individual scalar felds. The application, includes a graph viewer to plot the variation density function against isovalues and an Isosurface viewer to interact with Isosurfaces. The implementation is based on ideas described in [1].
