Worldmap Panel - Enter own locations

Hi together,

I play with the worldmap panel and I challange me into visualise with own city points. I have the testdataDB with a alias new-york, it works perfect. But if I enter my own JSON file like (…/town.csv):


it doenst work. I wanne display the value from alias new-york in my list as t1213 but something I take wrong. How is the right way?

Thank your verry much. Daniel
