From 6f88a59978cd9632dffc54ce2a588eb938deb392 Mon Sep 17 00:00:00 2001 From: Andrew Charlwood Date: Thu, 5 Feb 2026 19:39:34 +0000 Subject: [PATCH] feat: add chart type toggle for Directory/Indication views (Task 4.1, 4.2, 4.3) - Add selected_chart_type state variable and set_chart_type() handler - Add chart_type filter to load_pathway_data() WHERE clause - Create segmented control toggle component in filter strip - Add dynamic hierarchy label (Directorate vs Indication) -
