Shiny was really born out of this idea of reactive programming. It's about making it easy to program against values that are changing over time. You won't see as much here that you do see on Shiny for R is like interactive dashboards or even non interactive real time streaming dashboards. The actual like UI widgets for making something that looks like a dashboard is in Shiny for R, but not in Shiny for Python. So we have a new release coming that adds a lot more UI stuff.
