input: Write a function to generate a data visualization dashboard using Matplotlib in Python. The function should accept two lists, x and y, representing the data points for the x-axis and y-axis respectively. The function should create a plot with the given data points, set the title of the plot to 'My Data Visualization Dashboard', set the labels for the x-axis to 'X-axis' and for the y-axis to 'Y-axis', and show the plot. The function should return the figure object.
  
  assert generate_dashboard([1,2,3,4,5], [10,25,30,50,80]).get_axes()[0].get_title() == 'My Data Visualization Dashboard'
  assert generate_dashboard([1,2,3,4,5], [10,25,30,50,80]).get_axes()[0].get_xlabel() == 'X-axis'
  assert generate_dashboard([1,2,3,4,5], [10,25,30,50,80]).get_axes()[0].get_ylabel() == 'Y-axis'
  assert generate_dashboard([], []).get_axes()[0].get_title() == 'My Data Visualization Dashboard'
  assert generate_dashboard([], []).get_axes()[0].get_xlabel() == 'X-axis'
  assert generate_dashboard([], []).get_axes()[0].get_ylabel() == 'Y-axis'
output: def generate_dashboard(x, y):
      import matplotlib.pyplot as plt
      fig, ax = plt.subplots()
      ax.plot(x, y)
      ax.set_title('My Data Visualization Dashboard')
      ax.set_xlabel('X-axis')
      ax.set_ylabel('Y-axis')
      plt.show()
      return fig
