expandable svg component

Good afternoon everyone;
 
First of all I would like to thank your for creating such a resources for people like me to benefit from it. 
 
I am working on a small project for my university assignment  I need your help. Because i could not find an answer for what i am looking actually.
 
My problem is;
 
I was wondering that is it possible to do such a possible thing with just using svg. here is the image;

when user clicks on this svg component in stage-1 it will expand and show another graph inside.
When user clicks on graph in stage-2 it will return to stage-1 again. It is like expandable component. 
 
Thank you for separating time and reading this message despite your daily work.
 
Regards...
