Plotting Graph using jQuery

Here is the situation I am in.

My customer has a HTML page. On this html page he has a static html table with 2 columns. He wants to plot a graph by using values in column 1 on x axis and values in column 2 as y axis.

I want to use google charts for this.

The question is how can I use Javascript (JQuery) to parse the HTML table and then build the google chart URL?

Thanks for your help.
