If self-hosting is an absolute requirement, then you may want to consider another vendor, e.g. Highchart's OEM license <https://shop.highsoft.com/highcharts/#oem>.
Back to Google Charts: each chart type has a "Data Policy" section on their page. (For instance, Bar Charts <https://developers.google.com/chart/interactive/docs/gallery/barchart#data-policy>.) For each chart you are considering to use with the internal dashboard, you could check its "Data Policy" -- if it's of the type "All code and data are processed and rendered in the browser. No data is sent to any server." you could ask your client if this is acceptable to them. -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
