<｜begin▁of▁sentence｜>### Instruction:
Given a graph which you can read from 'graph98.gml', how would you visualize the vertices using the `MatplotlibVertexDrawer` class in igraph, integrating it with a matplotlib plot in Python?
### Response:
import igraph as ig
import matplotlib.pyplot as plt

# Reading a graph
g = ig.read('graph98.gml')

# Creating a plot
fig, ax = plt.subplots()

# Create a layout for our graph
g_layout = g.layout('kk')  # Kamada-Kawai layout

# Initialize the Matplotlib vertex drawer with the provided ax and layout
vertex_drawer = ig.MatplotlibVertexDrawer(ax=ax, palette=plt.cm.tab20, layout=g_layout)

# Draw the vertices
for vertex in g.vs:
    vertex_drawer.draw(vertex)

# Show the plot
plt.show()
