I am trying to generate a D3 Chart which one I am doing manually because there is no pluggin avilable for this. For this I am using 'HTML SNIPPET' and this is working properly but problem is "static json data". Now I want to make it dynamic means I wanna to get data from entity and display in graph. But I am not getting any way how to do this.
In this image I am trying to show html snipprt having static jSon data, this data I am showing in graph. How I can get this from entity?
