We are working with two data files. They contain the data that will be used for this section in terms of the vertices and edges that make up a graph:

graph1_edges.csv
graph1_vertex.csv

The vertex file contains just six lines representing the graph used in the last section. Each vertex represents a person and has a vertex ID number, a name, and an age value:

1,Mike,48
2,Sarah,45
3,John,25
4,Jim,53
5,Kate,22
6,Flo,52

The edge file contains a set of directed edge values in the form source vertex ID, destination vertex ID, and relationship. So, record 1 forms a Sister relationship between Flo and Mike:

6,1,Sister
1,2,Husband
2,1,Wife
5,1,Daughter
5,2,Daughter
3,1,Son
3,2,Son
4,1,Friend
1,5,Father
1,3,Father
2,5,Mother
2,3,Mother

Lets, examine some GraphX code samples.
