+### Committed: 02fe4b4 "feat: add Dosing Interval Comparison chart (Task 9.7)"
 ### Patterns discovered:
 - Dosing chart benefits from two distinct modes: overview (all drugs, weighted averages) and comparison (single drug, per-trust). The `group_by` parameter makes this clean without separate figure functions.
 - Trust names are very long (e.g., "NORFOLK AND NORWICH UNIVERSITY HOSPITALS NHS FOUNDATION TRUST") — stripping " NHS FOUNDATION TRUST" and " HOSPITALS" suffixes greatly improves y-axis readability.
