I'm pretty new with Carto. I have worked with Carto Editor one time in the past, but in Carto Builder I'm missing the "Merge -> column join" option.
I tried to create a map by using the two data sets I have (geodata from my city in Germany) and a dataset with statistics structured by zip codes. I marked both datasets and clicked on "create map". But somehow carto tells me, the dataset with the statistics has no geo reference.
What can I do?
