Abstract

Business data is often presented using simple business graphics.These familiar visualizations are effective for providing overviews,but fall short for the presentation of large amounts of detailedinformation. Treemaps can provide such detail, but are often noteasy to understand. We present how standard treemap algorithms canbe adapted such that the results mimic familiar business graphics. Specifically, we present the use of different layout algorithms perlevel, a number of variations of the squarified algorithm, the useof variable borders, and the use of non-rectangular shapes. Thecombined use of these leads to histograms, pie charts and a varietyof other styles.
