Comparing columns and reporting results in a Venn diagram

I want to compare the names in 4 columns. The output should be the number of names in common among all the columns and the names in common between pairs and triple columns. With this info, I would then draw a Venn diagram.

Thank you

Hi @al19

Welcome to KNIME Forum. @mlauber71 published a nice workflow on the KNIME Hub to create a Venn Diagram (with the use of R), see R Graphics - The Data Scientist Venn Gramm.
