I want to design a MLM diagram on webpage with dynamic data as below webpage,kindly suggest

Do you mean that if you hovered over an icon representing someone in the inner circle of salespeople you'd get a pop-up window of some kind showing their name and picture ?

What happens when you add new users at different levels, and/or you have so many users at some level you don't have room to represent them all as icons ?

I'd suggest you use a TreeView.

I was thinking of a TreeView working together with the circular graph: to solve the problem of having too many levels, too many sellers on any given level. The selected Node (with children) in the TreeView could be used to filter from the group of all sellers, to achieve visual clarity.

To implement a dynamic version of this kind of graphic display, linked to a database, for use on any given web-browser, would be a major project. You would almost certainly want to use a 3rd. party charting/graphing software library: unless you are an advanced web-programmer and have several months of time to work it out yourself.
