As I look at other BI/Analytics products, I have seen several that include a Sunburst visualization. I found this to be an interesting tool for following a trail of breadcrumbs in a visual way. For example, percent of sales by territory, starting at the inner ring (zone), then region, then country, then metropolitan area, just by hovering with my mouse.
I had a chance to try it out in another product this week, and I could immediately see the utility of it for sales analysis: not intended for a “deep dive,” but for a quick view I could see it being popular among executives.
