This paper presents a novel image caching strategy implemented for our bifocal radial visualization for Intranet search visualization. This visualization displays search results by combining hierarchical information with focus+ context. It is designed specifically for domain or Intranet searches, where specific search results are overlaid (highlighted) on top of a hierarchical circular visualization, which enables these results to be viewed in context with the whole dataset. Drawing large hierarchies is time-consuming, hence the main visualization is cached in a unique way to provide interactive visualization and manipulation. The caching is complicated by the use of the bifocal distortion where a portion of the visualization is magnified, thus two sets of images are cached. This paper describes the caching technique in detail.
