Regarding arguments made for "sunburst style visualizations", it is usually that in Sunburst visualizations the drawing space increases with each level as the circumference of the radial plot increases. This is useful for trees, which usually have more nodes to show on lower levels closer to the leaves, than on higher levels closer to the root. In comparison to the favored squarified treemap layout, sunburst visualizations are also able to represent an order in which the nodes may be given. Regarding a tree visualization for the contents, we tried this in the beginning, but it often needs a lot of "editorializing" to decide which class to put a visualization technique in, if it would fit 2 or even 3 classes at the same time. Hence for the web-version, I switched over to a plain list. The old hierarchical layout can still be found at https://cs.au.dk/~hjschulz/pdfs/treevispo.pdf https://cs.au.dk/~hjschulz/pdfs/treevispo.pdf
