I have fixed a bug in the handling of the translation files for charts and also made some changes to support loading the charts in a Modern Page.
This is done trough the new Modern CEWP that I have made available today: https://spjsblog.com/modern-cewp/
You find the change log here: https://spjsblog.com/spjs-charts-for-sharepoint/spjs-charts-for-sharepoint-v7-change-log/
