What is edge bundling function?

Dense networks often suffer from “hairball effect” - visual clutters due to large amount of nodes and edges. Edge bundling is a way to improve the readability of such network by using a process analogous to bundling network cable wires. This feature is available for both 2D and 3D visualization, with a short-cut icon bundling
