Their complexity poses a challenge to visualization systems, leading to issues such as scalability and visual clutter. Thus, we propose a radial layout-based visual exploration system to enable the user to smoothly explore the change over time and to explore different commodity classes at once by using a novel edge bundling concept. We evaluated our system with the aid of a group of domain experts.I.3.3 [Computer Graphics]Picture/Image GenerationGraphs and NetworksHierarchy DataTime Series DataGPUs and Multicore Architectures10.1111/cgf.13186273-282
