Simulations can be used to help formulate and solve complex problems. Toward this goal, the Arizona Center for Integrative Modeling and Simulation (ACIMS) is a research laboratory at Arizona State University that creates powerful tools for simulating complex systems. Their flagship simulator, DEVS-Suite, allows users to create models that can be simulated. The latest version of this simulator supports storing data in Postgres, a relational database that is well suited for storing millions of data points. However, though DEVS-Suite supports real-time visualizations, the simulator does not support the manipulation and visualization of the data stored in the database. As simulations become more complex, users benefit from visualizing time-based trajectories. User-defined data visualization can help gain new insight into generated simulated data.
