title: What is the 'Hello, World' for the Javascript InfoVis Toolkit?
body: <p>I am doing research in graph theory and need to visualize graphs in real time.
  (That is, if the graph data changes, its representation changes with it.)
  InfoVis seems to meet that goal, but I am struggling to put together a simple 'Hello, World' page that just displays a graph on-screen with clickable nodes (where clicking causes the node to change color).</p>
  
  <p>I have a working installation of JIT (the given examples work),
    I just need a minimal example of InfoVis to get started,
    and it is proving difficult to piece one together from the documentation.</p>
