Review on OnGraph by Russell Rabbach

I like that it is easy to use, has many features for both personal projects as well as large scale business applications. It's free if you're just using basic functionality (like charts). The interface can be clunky at times but there are plenty of tutorials online so figuring out how things work isn't too complicated. We've been able to build multiple dashboards with Ongraph in less than 2 weeks! Our dashboard allows our sales team members to easily view their performance compared against others within the same department or across all departments.
