Indicate if each of the two graphs are equal

The image consists of a graph diagram on the left and a matrix representation on the right.

**Graph Diagram:**

- It is a simple undirected graph with five vertices labeled as a, b, c, d, and e.
- The edges between these vertices are as follows:
  - a is connected to b and e.
  - b is connected to a, c, and d.
  - c is connected to b and e.
  - d is connected to b and e.
  - e is connected to a, c, and d.

**Adjacency Matrix:**

The matrix representation of the graph is a 5x5 matrix, where the rows and columns correspond to vertices a, b, c, d, and e in that order. The entries in the matrix are either 0 or 1, indicating the absence or presence of an edge between the vertices.

\[
\begin{pmatrix}
0 & 1 & 0 & 0 & 1 \\
1 & 0 & 1 & 1 & 0 \\
0 & 1 & 0 & 0 & 1 \\
0 & 1 & 0 & 0 & 1 \\
1 & 0 & 1 & 1 & 0 
\end{pmatrix}
\]

- The diagonal entries are all 0, indicating there are no self-loops.
- The matrix is symmetric, reflecting the undirected nature of the graph.
