fitting 2d normal distribution

Suppose I have 1d data that I want to fit with a normal distribution.  I
just compute mean() and var() and that's all I need to plot a normal
distribution fitting my data.

What about 2d data?  Are there ready-made functions for computing the
necessary parameters and plotting the 2d normal pdf?
