Design Suggestions

Hi I am completely new to software design and I am looking for some advice in how to structure my code. I am working on a basic html/javascript based web app that you can create (computer science) graphs with and visualises their traversals. I have heard of the phrase MVC design. What design pattern would you suggest I approach the problem with, given I will be dragging and clicking on lots of canvas elements? FYI: I am using the konva.js library for graphics. Thanks in advance.
