+# Phase 50 — Server overview line graphs
+
+The eight Server Overview statistic cards are replaced with actual Swift Charts time-series graphs. Each graph retains the current numeric value in its heading and plots up to 60 sampled values over time. This applies to Dashboard and Server Status. The six existing live rate charts remain unchanged above the overview graphs. The overview also appears in the other monitoring screens where it was previously used.
+
+Charts show raw counter trends (cumulative values for Queries, Bytes, Connections, etc.); the six charts above show per-second rates where applicable. Graphs populate as five-second samples arrive.
+
+Validation: `swiftc -frontend -parse WorkbenchReplacement/MainView.swift` passed in Linux. Native macOS compilation and UI testing have not been performed.
