"""
Draw an unstructured triangular grid as lines and/or markers.
Call signatures::
triplot(triangulation, ...)
triplot(x, y, [triangles], *, [mask=mask], ...)
The triangular grid can be specified either by passing a `.Triangulation`
object as the first parameter, or by passing the points *x*, *y* and
optionally the *triangles* and a *mask*. If neither of *triangulation* or
*triangles* are given, the triangulation is calculated on the fly.
Parameters
----------
triangulation : `.Triangulation`
An already created triangular grid.
x, y, triangles, mask
Parameters defining the triangular grid. See `.Triangulation`.
This is mutually exclusive with specifying *triangulation*.
other_parameters
All other args and kwargs are forwarded to `~.Axes.plot`.
Returns
-------
lines : `~matplotlib.lines.Line2D`
The drawn triangles edges.
markers : `~matplotlib.lines.Line2D`
The drawn marker nodes.
