What is the procedure to follow in order not to get the nodes overlapped on the graph which are with the same Latitude and longitude values?
(Note:: Nodes on the graph will be displayed with the configured latitude and longitude values)
Any help regarding this is highly appreciated.
You don't specify, but I assume that you are using the latitude and longitude as layout coordinates. If that is the case, then how you fix this depends on what you want it to look like, but you obviously have complete freedom of how to assign layout coordinates, so once you establish that you have a duplicate (or something 'close enough', which you would need to calculate) then you could appropriately offset the coordinates for each of the overlapping items.
