Energy systems are under pressure to transform to address concerns about climate change. The modeling and visualization of energy systems can play an important role in communicating the costs, benefits and tradeoffs of energy systems choices.
In this thesis, we introduce a visualization system that provides an interface for exploring time-varying, multi-attribute and spatial properties of a particular energy system. This system integrates several visualization techniques to facilitate exploration of a particular energy system.
These techniques include flow diagram representation to show energy flow, 3D interaction with flow diagrams for expanding viewable data attributes such as emissions and an interactive map integrated with flow diagrams for simultaneous exploration of spatial and abstract information. We also perform level of detail exploration on flow diagrams and use smooth animation across the visualizations to represent time-varying data. We finally, include evaluation results of our system collected from expert and inexperienced participants. These results reflect on overall effectiveness of our visualization system and the novel features we developed.
