There are several nice charts uploaded to CloudDB recently confirmed to work on GC v3.6 RC1, several are Overview and User Charts and may be useful for users looking for examples and Summary replacements.
Others are Python charts, but don't require to install additional packages so they work just enabling Python embedding with Python Home empty.
There are also plenty of uncurated charts you may found useful, to access them change the "Curated Only" selection on the upper left corner of Chart Download.
Thank to all the contributors, specially Marcen and J.L. García Pallero for carefully documenting what the charts do.
Users just doing tests, or using CloudDB like it was Strava thinking their data will be uploaded (it is not), please delete them once your tests are over.
Ale.
