It depends on where the data is kept.

If it comes from a Google Sheet then you can give various people permissions to edit the sheet. Unless you've specified which columns and rows are getting imported in the code then changes to the spreadsheet take effect as soon as the page is refreshed in the browser.

The same as if it comes from any other database, whoever has permission to update that can edit it.

If you've put the data in the code, as with most of the examples in https://developers.google.com/chart/ then whoever has access to the code needs to edit it.

If you've specified which rows and columns are being imported in the code, then those probably need to be changed as well.
