JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Access our Developers Page to start: http://developers.jotform.com/. Is it a graph within the form or a graph for reporting form data? If within the form, it's a widget yes. If for reporting, you can create it as an app. Please note that apps/widgets are all subject for approval.
