Label propagation demo for a simple graph

@Vini2 If this is an UN-directed graph, wouldn't the adjacency matrix look something like this?

 1.00 0.00 0.00 1.00 0.00 0.00 0.00
 0.00 1.00 0.00 0.00 0.00 1.00 0.00
 0.00 0.00 0.00 1.00 0.00 0.00 0.00
 1.00 0.00 1.00 0.00 1.00 0.00 0.00
 0.00 0.00 0.00 1.00 0.00 1.00 0.00
 0.00 1.00 0.00 0.00 1.00 0.00 1.00
 0.00 0.00 0.00 0.00 0.00 1.00 0.00

It could be something wrong the matrix version of my graph library for inserting entries. When I tried to replicate the graph above, this was the adjacency matrix that came out for me.

Neighbor Visuals

0 : -> A-> D
1 : -> B-> F
2 : -> D
3 : -> A-> C-> E
4 : -> D-> F
5 : -> B-> E-> G
6 : -> F

I guess the main question is what are the neighbors of 1 and 2 supposed to be? 0 and 1 in my context.
