I am working on a 2nd Dashboard that would benefit from this idea and it would make development so much easier. The researchers want the sampling error present on charts of forest inventory metrics, the sampling error that occurs at various scales tells the full story of the data. For last year's project, maps were not required so I used the Google charts API to design the charts (example chart). The current project needs maps, so I may be forced to use another development platform or figure out a way to feed URL parameters between the web map and charts in the dashboard.
