Comparison of indexes and visualisation on map

Hello! I am trying to compare three indexes like education, unemployment and social exclusion for a number of countries and then to visualise the result with the map viewer. I am trying to join, using the node joiner, the two of the three excel readers, but I think that it doesn’t make sense.

Would anyone know another way to do that?

Hey @loukas05,

please share same sample input data. Joiner node sounds very reasonable.

PS: Is your question aiming to “how to use KNIME for that” or “what other analysis can be done with the data”?
