:param mindim - The minimum dimension (height or width) of the output
SVG (default is 600).
:param dimensions - The (x,y) display dimensions of the output SVG.
Using this will override the `mindim` parameter.
:param dimensions - The (x,y) display dimensions of the output SVG.
I.e. this specifies the `width` and `height` SVG attributes. Note that
these also can be used to specify units other than pixels. Using this
will override the `mindim` parameter.
:param viewbox - This specifies what rectangular patch of R^2 will be
viewable through the outputSVG. It should be input as a 4-tuple,
(min_x, min_y, width, height), or a string "min_x min_y width height".
This is different from the display dimension of the svg, which can be
set through mindim or dimensions.
:param viewbox - This specifies the coordinated system used in the svg.
The SVG `viewBox` attribute works together with the the `height` and
`width` attrinutes. Using these three attributes allows for shifting
and scaling of the SVG canvas without changing the any values other
than those in `viewBox`, `height`, and `width`. `viewbox` should be
input as a 4-tuple, (min_x, min_y, width, height), or a string
"min_x min_y width height". Using this will override the `mindim`
parameter.
:param attributes - a list of dictionaries of attributes for the input
paths. Note: This will override any other conflicting settings.
