The Gauge Custom Tiles are now available in production!
Gauge Custom Tiles - Arc and Radial Gauges 
I would still love to hear feedback from anyone who voted on this feature request or is otherwise interested in Gauges. Does an arc gauge with the option to specify min-max and optionally specify static color ranges cover your needs?
We would love to make this a native platform feature, but haven’t had a lot of feedback on specific requirements. Now that we have a working example with the Gauge Custom Tiles, it would be great to confirm what’s critical and what’s nice-to-have.
