title: Tools for describing JSON schemas
body: <p>I'm writing a spec and need to describe some JSON objects. Big JSONs tend to get too confusing with text and tabs alone. Is there any online (preferably) tool to create diagrams like the ones on <a href="http://www.json.org/" rel="noreferrer">http://www.json.org/</a> or <a href="http://www.sqlite.org/lang_altertable.html" rel="noreferrer">http://www.sqlite.org/lang_altertable.html</a>. They use them to describe syntax, but, is there anything like it to describe JSON objects ? They are great to represent objects that are required, optional, arrays, etc. </p>
