Link to Chart.java

[mdewilde]

I maintain a Java library that produces valid json to use with Chart.js.

As an hommage to Chart.js, it's named Chart.java: https://github.com/mdewilde/chart

Do you have a policy regarding which projects you link to from the integrations section of your documentation?

In short, it'd be great to see Chart.java linked from there.

@mdewilde looks great, can you submit a PR that adds a Java section with a link to Chart.java repository (or website)?
