I should be able to see a graphical representation of build time per task and build time per recipe. We could also consider task type (configure, compile, install, package, etc). The visualisation method is TBC, but for build time per task we could consider floating bar charts (similar to what's provided by pybootchartgui). For build time per recipe we might consider treemaps and their variations. The graph(s) should be interactive (zoom, pan, hover over sections to display information and click sections to view details for a single task / recipe). I should also be able to hide the graph(s).
