I am assigned to use Vaadin to develop a map application which is required to use China map (whose provider is a China company) and Google map. This application requires showing some data such as sales, markers as well as background color on states, city (see attachment). I cann’t figure it out how to start. I do appreciate your help.
Please keep in mind that you’ll need to spend some time learning the concept of client side Vaadin development if you don’t have experience with it yet.
