- Add create_icicle_from_nodes() to src/visualization/plotly_generator.py accepting list-of-dicts from dcc.Store with NHS blue gradient colorscale, 10-field customdata, and matching text/hover templates from Reflex version - Add update_chart callback to dash_app/callbacks/chart.py rendering go.Icicle figure from chart-data store with dynamic subtitle - Title generation helper mirrors Reflex _generate_pathway_chart_title()
