Is there a simple way to display web form statistics as a table or graph in VSD using the data on my S-Drive, or do I need to save the results to a database first and then generate a table or graph using HTML? For example, let's say I create a survey with a single yes/no answer and male/female gender in Web Form Builder and I want to display the accumulated results as a bar chart immediately after submission. How would I go about doing that?

You wont be able to do this on S-Drive because you need some php to do it and that's not allowed at this time.
I would make it a suggestion.
