Where to buy it in Chennai

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

Fewest stops

Which single shop covers the most of this list — because visiting four shops on a festival morning is not realistic.

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
