Integrative research, involving the modeling of living systems at different scales, is becoming more extensively used in the biomedical community. For this reason, an open-source library, called MSVTK, is being implemented to fill the gap in software visualization solutions handling multiscale data. The library adopts state-of-the-art visualization and interaction techniques to solve the various challenges. The efficacy of the proposed software solutions is being demonstrated on exemplary problems collected from current biomedical research studies.
