Abhik,

I am certain there is a more general way to do this but I relied on the fact that you used Strings for the Left-hand Nodes and Entities for the right hand nodes. Some of the other "Graph Experts" here, like @Szabolcs Horvát will likely have a more universal way to do this sort of thing. -- In fact you may want to use his iGraph package but I am not that familiar with it since I rarely do graphs.

Graph[graphData2, 
 VertexLabels -> {x_String -> Placed["Name", Before], 
   x_Entity -> Placed["Name", After]}, 
 GraphLayout -> "BipartiteEmbedding", ImageSize -> Large]

to get

Regards,
