Here I have a small online example http://codepen.io/ivanalejandro0/pen/ZLMQoE, I hope it's useful to you.

I've borrowed it from @marcin-mazurek's demo for his es7 decorator port of this library, is not exactly the same though.
His library: react-render-visualizer-decorator
His demo: react-visualizer-demo
