Crate bevy_ym2149_viz 

Visualization utilities for bevy_ym2149.

This crate hosts all UI components, helpers, and Bevy systems that render oscilloscope, spectrum, and song-status information based on the data exposed by the core audio plugin. Applications should add Ym2149VizPlugin alongside Ym2149Plugin to enable the widgets and use the builder helpers to spawn their preferred UI layout.
