Raphael vs ZoomCharts

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.

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.

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.

gRaphael is a Raphael extension to help you easily create graphs and charts.

ZoomCharts patented technology called Charts-on-Charts, which allows to dynamically build multiple interactive charts inside one canvas object.

ZoomCharts is built for mobile devices. All native multi-touch gestures are built in. Data navigation and exploration is as native as it could ever be.

All ZoomCharts products have high level of interactivity available.

ZoomCharts are canvas based, as tested with default settings, more than 20 times faster as svg based competitor with same data and default settings. Video available on ZoomCharts youtube channel.

Most of ZoomCharts customers do comment that ZoomCharts Documentation is one of the best that they have seen

They responded to my issue/question really amazingly fast and that means I didn't have to halt my project development. Also the attitude was great.
