-- > Vertex is a node in Graph
Each vertex will have an id and a dictionary (actually it is adjacency list).
The dictionary is implemented as follows :
The key in the dictionary is the node which is connected to this vertex and its value is the weight of the edge that connects this vertex to this node
Eg : a is connected to b and the weight of edge is 1 and a is connected to c and edge weight is 2
The adjacency list looks like this
a ==> {
"b" : 1,
"c" : 2
}
