# Module DGraphView

    module DGraphView: sig .. end

View classes.

Each optional function `delay_node`, `delay_edge` and `delay_cluster` of this module may be used to indicate whether an element must be displayed instantaneously (if the function returns `false`) or may be delayed for latter display (if the function returns `true`). By default, each function always returns `false`. It may be set for returning `true` from time to time, improving efficiency.

    class type [['a, 'b, 'c]] view = object .. end

Graph widget derived from `GnoCanvas.canvas`.

    module type S = sig .. end

    module Make: functor (V : Sig.HASHABLE) -> functor (E : Sig.HASHABLE) -> functor (C : Sig.HASHABLE) -> S  with type vertex = V.t and type edge = E.t and type cluster = C.t
