How do I iterate over data collected by a form?

I have a simple form that I want to user to be able to add events with. I have the form set up to save the data collected, but now I need to be able to show the data in a list. How should I go about this? Thanks.

if your talking at the Grav form plugin, then you might want to look at the Data Manager plugin that basically shows data (from forms and other places). it iterates over any json data it finds in the data folder. Also you can define structure for specific kinds of custom data.
