Research direction

Investigate the ring progress chart component in VChart's source code to understand how min and max values are used. Look for existing handling of edge cases. The maintainers may have provided guidance in the comments. Implement a fallback strategy, such as not drawing the ring when max equals min, and ensure it does not break other cases.
