Integrate Google Charts as a macro?

I'm an experienced ASP.NET developer, but I'm new to Umbraco and I'm wondering what's best way to integrate Google Charts with the CMS.
I've created a ASP.NET macro that contains a couple of properties for setting name on the chart axes, but I'm not quite sure how to be able to add data to the chart via Umbraco.

I'm thinking in direction of something like two textfields (X and Y values) and an "OK" button that adds the values to the chart. Is this possible to do in Umbraco? The data to be added could easily be 10 values a day, therefore scalability is important.

All suggestions are welcome.
