Mind Map navigation

Hi, first of all I wanted to thank all the laracast team, especially Jeffrey. Thanks to his courses and a degree in computer science, I managed to get my first job! Now about the project I'm working on with Laravel, the clients would like a mind map to be able to navigate the site. The map will then have to update automatically every time a new post is entered. I was wondering if there was a library of some kind capable of doing this, do you know any?
