The core design challenge was making a four-arm study design spatially legible. A flat chart could not hold the relationships between treatment combinations across two years of data without becoming unreadable. Turning the data vertical and letting the towers be physically manipulated gave physicians a way to build their own understanding rather than be talked at by a slide.

Physicians could spin the towers to isolate specific study arms, tap to hide an arm entirely, and toggle individual data points on and off. A built-in tutorial walked new users through the interaction before they explored on their own.
