How to plot an Ellipse?

[xiant...@gmail.com]

Hello everyone,

I have read through the documentation to find a way to plot an Ellipse such as:

Ellipse(center=Point(0, 0), hradius=a, vradius=sqrt(a ** 2 - c ** 2))

but the plotting module seems not work on it.

from sympy.plotting.pygletplot import PygletPlot as Plot

So is there any tips?

Thanks,

or any other geometry entity, suppose I have this 'e'

 e = Triangle(Point(0, 0), Point(4, 0), Point(4, 3))

how do I plot it?
