Your question is very ambiguous. Since SVG is an image format then
this implies that you want an image of the expression somehow but
there are many different ways that an expression could be represented
as an image. Do you want an image of the tree or a typeset equation
(like from LaTeX) or something else?

That's just the contents of an SVG file. If you had an SVG file then
you could just read the file to get the string.
An SVG file represents an image but you haven't said what you want an
image of. Also you don't say *why* you want an SVG image. The usual
reason for wanting SVG is to have an image in a webpage but the
easiest and potentially best way to have a typeset equation in a
webpage (assuming that is what you want) is to use Mathjax in which
case you should just convert your expression to LaTeX:
In [3]: latex(x**2)
Out[3]: 'x^{2}'
