March 2025: Focused on reliability and stability in Grafana dashboards. Implemented a defensive fix for the Bar Chart rendering to prevent crashes when there are no numeric fields. This was achieved by adding optional chaining for fillOpacity, ensuring safe handling of undefined values. The change reduces runtime errors for users configuring charts with sparse data and aligns with our aim to harden chart rendering against edge cases.
