Struct ViolinState 

pub struct ViolinState {
    pub hover: Option<(usize, f64)>,
}

Persistent, observable interaction state (FC-3). The violin’s hover readout tracks the cursor’s exact position, so the stored hover carries both the group index (into densities()) and the value the cursor maps to.

Fields

hover: Option<(usize, f64)>

(group index, value-at-cursor) for the hovered silhouette, or None.
