Visualisation - Tableau

I am trying to visualize the data (DOI: 10.25337/T7/ptycho.v2.0/US.38362002) from Project Tycho, the map given below produced with Tableau visualization tool.


Do I have to have a column with the unique identifier in the data file that is uploaded in the Tableau visualization tool?

Hi 992559,
Without knowing your data and what you want to visualize, it is hard to discuss your design. Could you post more information?
