Hohli

Holi is a nice site for creating online charts or diagrams. This is done w/ a very easy user interface and allows users to just enter data into a predesigned template. Then a user chooses the type of chart they want to create: bar, line, pie, etc. Best of all a user can save or embed their finished chart into a site/blog.

I highly recommend checking out Holi by clicking here!!
