SAPUI5 Using ODATA with Google Visualization and JSON

Hello Community, I am working now with SAPUI5 and maybe here are some people who know some answers 😊.

I try to get a timeline diagram by using the tools from google visualization. These are some verry good tools but they are not direct compatible with

sap.ui.model.json.JSONModel .

I need to transfer the data comming from the JSON Model to google.visualization.DataTable so i can use it with google.visualization.drawChart

maybe you have an idea

thx christian
