Hi @Nick_Trout -
@tapiocaPENGUIN is correct. Charts is still supported as a component of Atlas, and is being continuously updated with new features.
The on-prem version was discontinued last September. We did include a notice about this for around a year before support ended, and have since removed mentions of on-prem from the website. I was just made aware that some of the old documentation can still be accessed via a deep link - I’ll look to add a notice about the product being unsupported on those pages.
thanks
Tom
