Pros
Pro Works with older browsers
Because Raphael supports rendering VML + SVG, it is one of the few drawing libraries that is backwards compatible with older browsers that do not support canvas.
Pro Built in animations
Several built-in animations (such as ways of easing) are provided for you out of the box, but Raphael also allows cubic beziers for more complicated easing functions. Any drawing object property can be modified making it similar to css animations in jQuery.
Pro Every object is interactive with events
Everything that is drawn in Raphael is an object which means it is easy to manipulate any part of the rendered image after it is processed. It uses an event handler system for user inputs which makes it easy to learn for JavaScript developers used to event based libraries.
This style of handling objects makes Raphael a good fit for rendering interactive diagrams and charts that can also interact with other parts of the page.
Pro Easy creation of charts with extension
gRaphael is a Raphael extension to help you easily create graphs and charts.
Pro Many chart types available
There are more than 20 types of charts available for use.
Pro Wrappers for ASP.NET, ASP.NET MVC and Apache Wicket
Each chart can be implemented to ASP.NET and ASP.NET MVC applications, with detailed documentation and guides for each.
Pro Good documentation
Each of the available charts has documentation and guides available for every different implementation (JavaScript, ASP.NET etc.)
Pro Interactive charts
The charting widget is built to facilitate client side interactions and notifications.
Pro Out of the box pan-and-zoom
Zoom-in on specific points of interest on the graph with the mouse – a single property allows this out-of-the-box.
Pro Supports combining different charts
You can combine different charts (they can be of the same type or even different types of charts) to display data correlations.

Con Can be difficult to get support
