In a pilot study, we found that the sunburst chart was least preferred. In a controlled study with 12 participants, we compared treemaps, icicle plots and sundown charts. Treemap was the least preferred and had a slower performance on a basic navigation task and slower performance and accuracy in hierarchy understanding tasks. The icicle plot and sundown chart had similar performance with slight user preference for the icicle plot.  \nIndex Terms: Human-centered computing—Visualization—Treemaps; Visualization design and evaluation methods  \n1 INTRODUCTION  \nHierarchically organised quantitative data occurs in wide variety of contexts such as budget reports, CPU resource use, share portfolio allocation, and disk use. A number of different visualisations have been suggested to analyse such data [33] . The best-known is the treemap [23] . This is included in most modern data visualisation tools including Tableau and Microsoft Excel. Alternatives include the icicle plot, recently used to show “stack-traces” [20], and sunburst charts, used to visualise space allocation on a hard-disk [12] .  \nHowever, to date there has been no comprehensive evaluation comparing the effectiveness of these three visualisations. Past evaluations [4, 18, 39] have used small flat datasets, provided only very limited interactive navigation and/or used low resolution displays. The main contributions of this paper are:  \n• A novel visualisation, sundown chart, a semicircular variant of sunburst chart that is better suited to the wider aspect ratio of modern displays and reduces user disorientation during zooming.  \n• A carefully designed interactive navigation framework that is consistent across the four visualisations. This combines overview + detail, in-place zooming, breadcrumbs and uses unit visualisation [14] to reduces user disorientation during zooming.  \n• A hybrid WebGL and D3 implementation that allows responsive interactive visualisation of large quantitative hierarchies with more than 50,000 nodes using standard internet browsing tools.  \n• User evaluations of the visualisation designs. An initial pilot study with 6 participants compared all four visualisations. Feedback indicated that the sunburst chart was the least preferred. A second controlled study with 12 participants compared icicle plot, sundown chart and treemap. Treemap was clearly the worst, leading to slower performance task accuracy as well as being the least preferred. The icicle plot and sundown chart had similar performance with a slight user preference for the icicle plot.  \n2 RELATED WORK  \nTreemaps, see Fig. 1(c), use a space-filling design in which area denotes the quantitative node attribute and inclusion the node hierarchy [23] .

The original “slice-anddice” algorithm [23] led to nodes with high aspect ratio and unstable layout when the level of detail changed. Subsequent algorithms were designed to reduce aspect ratios [8, 43] and to improve layout stability [6, 38] .  \nIcicle plots, see Fig. 1(a), were originally developed as a method for presenting hierarchical clustering [27] . They use length to represent the quantitative attribute and juxtaposed layers to denote the hierarchy.
