Interactive visualization of electrical power flow using a schematic map

The Cartographic Journal.
This article introduces EFlux, an interactive visualization software that uses a diagram‐oriented representation of the Swiss extra‐high‐voltage electric grid. We explain the design principles used to visualize the network. Built on the seminal work by Harry Beck (London Underground tube map), it loosely maintains geographical locations, while conveying the topology of the network in a readable manner. The software blends quantitative and qualitative data with the map information, showing the dynamics of the network. Measurements at the substation and power line levels are mapped to graphical features (colour, thickness, line style). Animation is used to show how energy flows through the network. We describe how we use interactivity to navigate the schematic map, revealing more details upon zooming and selection, as well as how history can be replayed at comparable time intervals. Finally, potential improvements are discussed as part of our future plans.
