How to draw a multipolygon mesh

[mz12345]

Here Ive loaded the points of a multipolygon feature layer (taken from web json file). The color is meant to indicate the order in which the points were provided and they appear to be ordered and forming an outline of the mesh. 

I dont know what technique to use to "fill" this outline, to make a mesh out of it.

I am also wondering if there is a way to visualize a polygon created by ArcGISPolygonBuilder. Have you figured out a solution yet?
