I'm one of the Visor engineers, and you've stated perfectly what many of our users are running into. In addition to creating these "good-lucking diagrams for executives" (which is time consuming in itself), people need to keep them up to date. So they waste so much time updating the raw Jira data that feeds their charts. If we could get all of that data, make it "live", and put it in a spreadsheet so you could roll it up in whatever way you want, making those diagrams becomes trivial!
