This example visualizes a collection of iOS build errors, specifically highlighting missing frameworks such as FBSDKCoreKit, Bolts, and FBSDKLytroKit across multiple architectures (x86_64, armv7, armv7s, arm64). The visualization shows how these errors cluster and repeat across different build configurations. The code uses Swift and likely leverages a force-directed graph layout, as implied by the filename `faq_01.swift`, though the rendering approach is not explicitly detailed in the provided snippet. It presents the error messages as nodes to reveal patterns in dependency failures.
