WSO2 DAS. Vizualization event points on the map

Question

I would like to test GEO map gadget using WSO2 DAS. I have a stream with geo coordinates (e.g.: latitude=51.509865, longitude=-0.118092). My goal is to show points on the map in real time (real time datasource) using Geo Map chart type. I set only Id, latitude and longitude properties (default for others). In the result I see the map without points any points. I cannot find detailed information and examples in documentation. Is it possible or I have to use GPL - Siddhi Geo Extension?
