For your graph you should should try with pyplot.table:

import matplotlib.pyplot as plt
import numpy as np

board = np.zeros((10, 10))
board[0,0] = 1
board[0,1] = -1
board[0,2] = 1
def visBoard(board):
    data = np.empty(board.shape,dtype=np.str)
    data[:,:] = ' '
    data[board==1.0] = 'X'
    data[board==-1.0] = 'O'
    plt.axis('off')
    size = np.ones(board.shape[0])/board.shape[0]
    plt.table(cellText=data,loc='center',colWidths=size,cellLoc='center',bbox=[0,0,1,1])
    plt.show()

visBoard(board)
