Display Data with Google Charts

I am looking for someone to help with some fairly simple HTML programming using JSON and google charts. I am developing a simple data logger which records various data from some industrial equipment. This data is then pushed to a [login to view URL] server. I need some help developing an html page which pulls data from this server and graphs it using Google Charts. I also would like some simple data processing to be preformed. I have a working prototype which pulls the data and makes a very simple graph. I would to add additional features to this html page. I also would like to pull some of the data and do a few very simple calculations. Such as being able to display a daily average of some of the data sets.
