This is a simple example of an IPython notebook, which I Published using SageMathCloud's new "Publish" button.

In [13]:
import numpy as np
import matplotlib.pyplot as plt
N = 500
x = np.random.rand(N); y = np.random.rand(N)
colors = np.random.rand(N)
area = np.pi * (15 * np.random.rand(N))**2 # 0 to 15 point radiuses
plt.scatter(x, y, s=area, c=colors, alpha=0.5)
plt.show()
In [7]:
import math
plot([math.sin(x/10.) for x in range(0,60)])
Out[7]:
[<matplotlib.lines.Line2D at 0x7f0312203810>]
