Why does this most basic comp using Make Mesh with Values produce a black screen?

And a really stupid newb question -- what precisely is an element in this context?

To use the Parabox Make Mesh

To use the Parabox Make Mesh with Values node, you need to understand the basics of meshes. I would recommend spending some time reading or watching videos to understand the background.

To answer your immediate questions: For the node to output a non-empty mesh, it needs at least 3 vertices (Positions and Elements) as inputs. Elements are indices into Positions (0 refers to the 1st item in Positions, 1 refers to the 2nd item in Positions, etc.) that have to do with how the mesh is assembled.
