Struct ChartState 

pub struct ChartState {
    pub kind: ChartKind,
    pub hover: Option<(usize, usize)>,
}

Persistent, observable interaction state (FC-3): the current chart kind and which (series, point) the pointer last hovered. Serialized so it round-trips through the headless JSON seam.

Fields

kind: ChartKind

hover: Option<(usize, usize)>

(series index, point index) under the pointer, or None.
