This is a sunburst diagram (a kind of radial tree map), but it has not been generated from HOPEX ; there is no such renderer as part of the reporting toolkit.
from a treeset we can generate :
- dendrograms, in radial style if applicable
- tree maps (the closest to a sunburst, when using the components count for item proportions computation)
- breakdown report
- tree tables
note : to generate a sunburst from HOPEX data, you can for example generate a treetable from a treeset, export to MS Excel, rearrange the data in MS Excel as needed, and create a sunburst chart (or use another dataviz tool)
