The SVG file was created by running the following command on the input above:
mptopdf triangle.mp
and using the [http://www.tlhiv.org/MetaPost/tools/mptosvg/ MetaPost to SVG Converter], which basically does the following:
pstoedit -page 1 -dt -psarg "-r9600x9600" -f sk foo-1.pdf foo-1.sk
skconvert foo-1.sk foo-1.svg
