title: How do I display a proof tree with HTML,CSS and/or Javascript?
body: <p>I want to display a proof tree in the style of a natural deduction within a web page.
  I will get the data from a JSON file. </p>
  
  <p>Whats the best way to display something like this?
  Is it possible only with css? 
  Or is there a library that can do something like this?
  Rendering as an image is not possible, because eventually it should be interactive.
  I should also mention that this tree can get fairly large.</p>
  
  <p>Example: 
  <img src="https://i.stack.imgur.com/REVAm.png" alt="proof tree"></p>
  
  <p>Update: A better example of what the end result should look like:
