Circle demo yields an ellipse!

[Owen]

The first example here:
http://www.sagemath.org/doc/html/tut/node21.html
.. shows creating a circle plot via:
L = [[cos(pi*i/100),sin(pi*i/100)] for i in range(200)]
p = polygon(L, rgbcolor=(1,1,0))
p.save() ## or p.show()

When I try this, I get an ellipse! Or more precisely, the plot has
unequal axis scaling.

Here's a picture:

Good catch. Maybe the documentation should be updated to use

p.show(aspect_ratio=1) ?

Use this instead:

L = [[cos(pi*i/100),sin(pi*i/100)] for i in range(200)]
p = polygon(L, rgbcolor=(1,1,0))

p.save(aspect_ratio=1) ## or p.show()
