The full potential of information visualization is often not tapped in the scientific reasoning process. To overcome this gap, this work aims at bringing visualization closer to demands of the analysis process for the domain of modeling and simulating cell biological systems. Based on the identification of main segments of visual support that need to be provided, this work provides novel contributions for the visualization of stochastic simulation data. Two main visualization challenges are addressed. First challenge is the visual integration of data into the data generating context. A general approach for stochastic simulation data captures the process of data generation by four process levels: model, experiment, multi-run simulation data, and single-run simulation data. Tailored visualization concepts at all levels support the exploration of the complete simulation process rather than single simulation data sets. Second challenge is the visualization of large and complex data sets. Within the application domain, simulation data incorporates heterogeneous data types and is given in temporal, spatial, and multivariate context. New visualizations handle this challenging complexity by the combination and close linkage of multiple views, each revealing different aspects in the data. The novel visualization concepts have been made available in a visualization component library.
