Change visualization in view mode

When you are designing a report, you can change the visualization type/chart so as to choose which one suits best according to your preference. It would be great to have some sort of possibility to this regard when viewing the report in read-only mode. In other words, just as I interact with the report in several other ways (ordering data, filtering, slicing, drilling, etc) another option would be changing the type of visual on-the-fly. I realize this will most probably be quite tricky, and could actually involve complex logic regarding what changes make sense or not (although it could just work the same as when designing the report), but it would be amazing for users.
