diagram.links()

diagram.links()

Returns the Delaunay triangulation of the specified data array as an array of links, one for each edge in the mesh. Each link has the following attributes:

• source - the source node, an element in data.
• target - the target node, an element in data.

Since the triangulation is computed as the dual of the Voronoi diagram, and the Voronoi diagram is clipped by the extent, a subset of the Delaunay links is returned.
