Jquery Graphs

Recently I had to come up with a low cost graphing solution for one of my clients, little did I know that Jquery Graphs would not only be a fringe tools, but something that can be used professionally as well. That said there are both paid and free tools which meet professional standards and are as good as it gets features available. some of the key pro and cons of using jquery graphs are listed below 

PROs

1. Light weight and very small foot print 
2. Client side control, so resources are not consumed on the server, and jquery calls can be made to get real time data or read of a XML
3. Interactive UI, clicks on graphs and specific bars or section can be handled in most tools available.
4. Easy to implement
5. Most Important fact is that most of these are actually HTML 5 compliant and render well on all modern browsers

CONs

1. Lacks support in older browsers support, though they us excanvas.js it fails at times
2. If you opt for a free tool, you may struggle to find support on the tool
3. can be complex to use with AJAX or other scripting libraries.

Some of the tools i reviewed are listed below in particular order

1. JQPlot - Free but an advanced library 
2. HighCharts - Paid but really good.... you pay $80 for a single site without any login or user based data, but if you have a login and user based data then the price moves to $360.
3. Flot - Good but the library lacks good examples and documentation and is sightly harder to work on.
