This visualisation shows a proportional map of which projects and tasks you assign time to. The inner-ring represents projects and the outer-ring, tasks assigned to these projects.
I wanted to see how I was distributing my time amongst the various projects, and this sunburst diagram makes it easy to see the breakdown at both task and project level at a glance.
