How to create a weighted graph and evaluate all the shortest path bet

Sorry to ask this question but I cannot see how to start. I have a graph with say 3 vertex ${1, 2, 3}$. The weights are :

1-2 : 6 1-3 : 2 1-4 : 2 2-3 : 1 2-4 : 5 3-4 : 3

I would like to know how to create such a simple graph in such a way to be able to evaluate the shortest path between any pair of two vertices. I have found how to do that for simple graphs not for weighted.
