Dashboards

[mavam]

In addition to the pipeline overview, we need a high-level dashboard page with management-grade KPIs.

We are looking to build this out as an evolution of the Explorer and Data Visualizer, and want to allow users to pin results to a dashboard. Initially, this will be restricted to historical data sets only, i.e., charts will not update live.

We had conversation with a prospect who said that a dashboard would be important.

We spoke to another person who mentioned that solid dashboarding would make a huge difference.

Should we add the story on grouped & stacked bar charts to this epic? ARo also said it's important to him.

Can you update the story list in the OP with that? Otherwise the current state is difficult to capture.
