title: How to create a UML Class diagram with react JS
body: <p>I'm newer in Web developpement (I have modest knowledge about it).
  I'm asked in my university-project to develop a webapp that generates a UML class diagram using ReactJS.
  I've installed nodeJS, webstorm, I tested a "hello world" code, it works but I don't know how to generate this digram, from where start.
  In reality, I've tested the library storm-react-diagram, but I didn't get any result.
  Please , someone can help me, orient me or propse me any template, any code that works to be inspired. really I'm lost.</p>
  
  <p>Thanks</p>
