@param nodes [Array<InventoryRefresh::InventoryCollection>] List of Inventory collection nodes
 Returns graph in GraphViz format, as a string. So it can be displayed.

 @param layers [Array<Array>] Array of arrays(layers) of InventoryCollection objects
 @return [String] Graph in GraphViz format
@param nodes [ Array<InventoryRefresh :: InventoryCollection > ] List of Inventory collection nodes Returns graph in GraphViz format as a string . So it can be displayed .
