+    Draw a unstructured triangular grid as lines and/or markers.
+
+    The triangulation to plot can be specified in one of two ways; either::
+
+      triplot(triangulation, ...)
+
+    where triangulation is a `.Triangulation` object, or
+
+    ::
+
+      triplot(x, y, ...)
+      triplot(x, y, triangles, ...)
+      triplot(x, y, triangles=triangles, ...)
+      triplot(x, y, mask=mask, ...)
+      triplot(x, y, triangles, mask=mask, ...)
+
+    in which case a Triangulation object will be created.  See `.Triangulation`
+    for a explanation of these possibilities.
+
+    The remaining args and kwargs are the same as for `~.Axes.plot`.
