Getting GraphViz to eliminate identical duplicate edges

Question

I have the following .dot language file for GraphViz:

digraph {
    graph [ dpi = 300 ];
    Hello -> World
    Hello -> World
    Hello -> World
}

Which renders as:

But I don;t want the duplicate links i.e. I want it to render as:

Yes, I could add logic to the program that produces the dot file, but if there is a GraphVix parameter to do this it’d be very useful.

Thanks.

Edit: Raising the dead here, but the question of which this is marked as a duplicate has multiple connections between 2 nodes but each with different labels, so not exactly the same, although the suggestion to use the ‘strict’ keyword does work.

Voted to reopen as the question that it is marked as a duplicate of, and the cause of the close votes, isn't a duplicate. — Steve Ives, Nov 30 '21 at 11:00
'Original' question edited because the title was incorrect, leading to the confusion perhaps that this is a duplicate. The edges in the other question are NOT the same but have different labels. — Steve Ives, Apr 07 '22 at 09:37

‘strict’ was the answer :

strict digraph {
    graph [ dpi = 300 ];
    Hello -> World
    Hello -> World
    Hello -> World
}
