You are free to use the data and all available graphs on the site in any way you like. If you are feeling generous, link back to the site so
that other people can also find out about it.
The graphs are plotted for data in last 48 hours. If you need data for lets say a week or a month,
drop me an email at (himanshu <dot> baweja <at> gmail <dot> com) with url of your site and what data you need.
Depending on your requirement, I might give you access to backend admin panel or if its a one-time request just generate and send over the graphs.
