DagChart

Struct DagChart

pub struct DagChart<'a, S, V>where
    S: Schema,
    V: View<S>,
{ /* private fields */ }

Expand description

The dag-chart widget.

A dag-chart represents each unique tuple of the view’s display dimensions as a path in a directed acyclic graph. Paths with common sub-paths, starting from the primary dimension (1st), are collapsed in the frame.
