Visualization

Definition

Visualization is the process of creating visual representations of data or simulations to help interpret complex information more clearly. In the context of astrophysical simulations, visualization plays a critical role in revealing patterns, structures, and behaviors of astronomical phenomena that are otherwise difficult to understand. It allows researchers to gain insights into the dynamics of celestial objects and the underlying physical processes through graphical representation.
