The network shows people who communicate directly. Each line is one direct two-way communication link
Use this vertex order for both the rows and the columns of \(M\): Maya, Liam, Noah. Rows name the starting vertex and columns name the ending vertex
\[M = \begin{bmatrix} 0 & 1 & 0 \\ 1 & 0 & 1 \\ 0 & 1 & 0 \end{bmatrix}\]
