Yes, you can use the visualization API in commercial projects ( http://code.google.com/apis/chart/interactive/faq.html#commercialuse, section 6 of the Terms of Use<http://code.google.com/apis/chart/interactive/terms.html>). If you use the interactive charts (as opposed to the image charts), none of your data goes through Google's servers (see the Data Policy section for the charts you use, ex: http://code.google.com/apis/chart/interactive/docs/gallery/areachart.html#Data_Policy ).
You can't use the charts offline or download/host any of the code, however ( http://code.google.com/apis/chart/interactive/faq.html#offline, http://code.google.com/apis/chart/interactive/faq.html#localdownload, section 5 of the Terms of Use<http://code.google.com/apis/chart/interactive/terms.html> ). -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
