I have a feed which queries USGS for Data. I am taking that data and putting it into node form and creating views from that data.

What I would like to do is to create a simple line graph showing changes of this data over time...I cant seem to get this to work...Anyone care to explain the best way to get this done. I am stripping all the html and data from the view and left only with the data and time requested and the actual decimal data that is provided.
