Are there external flowchart apps that can be linked and interactive on a website?


I’m pretty novice to creating my own website. I had this idea of which I would have an integrative flowchart on my website for people to click on to follow the different blog posts that branched into different directions. Does such an app exist? Am I living in a make-believe perfect world where I can throw anything I want into a rigidly structured bunch of 1s and 0s?

Please help bring me down to earth.
