Demo Abstract: Visual Analytics of Higher-order Dependencies in Sensor Data

Existing approach to model sensor movement data as pairwise connections in networks implicitly assumes the Markov property and loses higher-order movement patterns. While the higher-order network (HON) captures higher-order movement patterns, there has not yet been a visualization tool tailored for HON. Based on our prior work, in this demo we present HoNVis, a comprehensive visualization and interactive exploration framework for HON. We demonstrate domain experts' workflow for analyzing global ship movement sensor data with HoNVis.
