Karthigai Deepam
Rows of clay lamps along every wall and threshold. Second only to Diwali for diya and oil demand in the south.
Where to buy each item
Every item on the list, resolved to a shop that has it in stock.
A four-hop traversal. The trailing variable-length step is what lets “Chennai” match a florist registered in T. Nagar without you having to know that.Occasion → NEEDS → Product → AVAILABLE_AT → Florist → LOCATED_IN → Location → PART_OF*0..3

The full checklist
Grouped by category, essentials first. Quantities and notes come from the relationship between this occasion and each item.
The quantity, the unit, the importance and the note all live on the NEEDS relationship — not on the flower and not on the occasion. That is the clearest single argument for modelling this as a graph.Occasion → NEEDS → Product → BELONGS_TO → Category
