Need graph that consolidates multiple inputs from dropdown form

1. I need a template that allows a user to select a location from a dropdown menu (Cell B1 of Example Data tab).
2. Titles in cells C1:V1 and B2:B8 will stay the same.
3. Data inputs within range C2:V8 would change for each location. The idea is based off the location selection from the dropdown menu, different data is shown within the range and available for updates.
4. The chart (see Example Chart) would sum all location inputs in range C2:V8
