01 Challenge & Context

LEGO enthusiasts and collectors struggled to evaluate investment value, piece-to-price ratios, and historical theme lifecycles from static catalogs.

02 Solution & Execution

Extracted and transformed multi-decade catalog datasets using Python and Power Query, building dynamic scatter plots and theme distribution hierarchies.

Key Design Decision

Developed an intuitive price-per-piece efficiency matrix allowing users to spot exceptional value sets at a glance.

Trade-off: Price per piece makes comparison approachable but cannot represent rarity, condition, or resale value alone, so it is presented as an exploration aid rather than buying advice.
