How to visualize NLTK python results in web?

I'm a newbie to python. recently i have tried some python programming in NLTK. I found this website that display the output in a colorful way. similarly i need to display my output in a webpage. I find out Django and flask are some frameworks that allow python go web. However i wonder how NLTK output display in a browser. i'm very curious to get to know. please don't ignore my very basic question for the pros'.
