The central aspect of a Graphical Model is the representation of dependencies among random variables. Graphical models are structured representations that utilize graphs to illustrate how different variables relate to each other, capturing the conditional dependencies via edges connecting nodes that represent the variables. This graphical representation simplifies complex relationships and helps to visualize the interdependence of multiple random variables, making it easier to model and understand probabilistic relationships in a system.

By depicting these dependencies, graphical models facilitate reasoning about the probabilistic relationships, which is fundamental in various applications such as Bayesian networks and Markov random fields. This allows practitioners to derive insights and make inferences based on the structure of the model. While aspects like performance, visualization, and learning frameworks are relevant in the broader context of computational methods and applications, they do not encapsulate the core purpose of graphical models, which is to provide a clear and intuitive representation of how different variables interact with one another.
