Problem statement: I want to show some features (or descriptions) over the state diagram, but not as description in the box. It should be shown, whenever I hover on it. One close feature I got was of HREF. But that do works on a word. That is, when I hover on a particular word, it shows the link on a small pop up type thing.
I want to implement the same thing on hovering over a state. How can I do that using href? Or is there any other way for the same?
