Description

After Sprint 7 theme integration, choropleth maps are not displaying on the Toronto dashboard. This is a carryover debugging task from Sprint 7.

Context

Sprint 7 implemented:

  • Dark theme with MantineProvider
  • Floating sidebar navigation
  • Updated figure factories for dark theme support

Symptoms

  • Maps not rendering on /toronto page
  • Callback may not be triggering or returning empty figure

Investigation Areas

  1. Callback Registration

    • Verify map callbacks are registered correctly
    • Check if callback is being triggered (add print statements)

  2. Figure Factory

    • Confirm create_choropleth_figure() receives correct data
    • Check GeoJSON data loading

  3. Theme Integration

    • Verify carto-darkmatter map style works
    • Check if transparent backgrounds affect rendering

  4. Data Loading

    • Confirm demo data is loading correctly
    • Check for any parsing errors in GeoJSON

Priority

High - Core dashboard feature not working

Carryover From

Sprint 7 (#27)

Closing as won't do — The choropleth maps will be completely rebuilt for the new neighbourhood-based dashboard. The TRREB district maps this issue references are being removed. See docs/changes/Change-Toronto-Analysis-Reviewed.md for the new implementation plan.
