Abstract
Parallel coordinates are a well-researched visualization technique to represent multidimensional data. There are many variations of parallel coordinates for different application needs. This report describes a visualization solution for large multidimensional data. The report also proposes an evaluation plan to investigate non-linear data relationships through variants of parallel coordinates. Based on this proposal, a web-based application of bundled parallel coordinates was designed and implemented. This visualization supports different clustering methods and violin plots to discover data distribution. It also has a series of interaction features such as brushing, reordering of axes, and zooming. A pilot study was also conducted to evaluate the perception of non-linear data relationships through variants of parallel coordinates, and the results helped the formation of a hypothesis: interactions help the discovery of non-linear data relationships, and standard parallel coordinates can better support such tasks than bundled parallel coordinates. An evaluation is needed in future work to evaluate this hypothesis.
