RRDTools under win7 possible?

Hello,

My draft measure pH-Temperature-redox etc ... my pool, I recorded the data on LCD but was told about RRDTools I could send it as a graph.
Unfortunately I do not know.
I read in Oeticker (Switzerland) that the software was for linux or not?
I work under win7.
Can anyone tell me if I can download in win7 RRDTools and thank you to tell me how because the website Oeticker is that difficult to understand.

thank you.
Georges
