May be its something like wireframe. I Think its just a mock up they are looking for.
May be they want to know how u r about to pull data into qilkview, do data modeling and how their ui would look at last.
Ask for some sample data or create some if u know how the data is going to be present there. Create ODBC connections to pull data, do data modeling with the sample u created and create the required charts. and create a sample dashboard.
