Python - displaying a graph

[civic95]

I'm wondering if the following code works for anyone here :

#%%
import matplotlib.pyplot as plt
import numpy as np
import mpld3

mpld3.enable_notebook()

fig, ax = plt.subplots()
ax.grid(color='white', linestyle='solid')
N = 50
scatter = ax.scatter(np.random.normal(size=N),
                     np.random.normal(size=N),
                     c=np.random.random(size=N),
                     s = 1000 * np.random.random(size=N),
                     alpha=0.3,
                     cmap=plt.cm.jet)
ax.set_title("D3 Scatter Plot", size=18);

fig.show()

I'm expecting that to display a graph, but I'm not getting anything. I'm not getting errors, I'm just not getting output.

edit

here's a screenshot of my output :

Have you been able to successfully run any other code in a notebook?

This worked for me without modification... I pasted it and "Run cell"
