I believe the SDK uses openlayers / geoext but makes the creation of map applications user friendly? I just need to know what to use each for in the terms of a new user
I want to create an app that displays layers, I have done that with the SDK pretty easy with GXP. However I also want to add graphs/charts to the maps, this is where I am unsure which route to go down. The user would click on a point and would be able to view a chart of that points change over time.
