Suppose for the data like below, by default it should show countries and when user selects a single country IN then it should show IN, UP,MP,AP as the dimensions and when user selects UP then should show UP,LK,RA as dimensions.
Country State City Sales
IN UP LK 10
IN UP RA 15
IN MP BP 20
IN MP JB 25
IN AP VZ 30
IN AP BZ 35
In short, I should show both parent and it's child value in bar graph.
Any suggestions please.
