"""Takes in a list of paths and creates an SVG file containing said paths.
REQUIRED INPUTS:
:param paths - a list of paths
OPTIONAL INPUT:
:param colors - specifies the path stroke color. By default all paths
will be black (#000000). This paramater can be input in a few ways
1) a list of strings that will be input into the path elements stroke
attribute (so anything that is understood by the svg viewer).
2) a string of single character colors -- e.g. setting colors='rrr' is
equivalent to setting colors=['red', 'red', 'red'] (see the
'color_dict' dictionary above for a list of possibilities).
3) a list of rgb 3-tuples -- e.g. colors = [(255, 0, 0), ...].
:param filename - the desired location/filename of the SVG file
created (by default the SVG will be stored in the current working
directory and named 'disvg_output.svg').
:param stroke_widths - a list of stroke_widths to use for paths
(default is 0.5% of the SVG's width or length)
:param nodes - a list of points to draw as filled-in circles
:param node_colors - a list of colors to use for the nodes (by default
nodes will be red)
:param node_radii - a list of radii to use for the nodes (by default
nodes will be radius will be 1 percent of the svg's width/length)
:param text - string or list of strings to be displayed
:param text_path - if text is a list, then this should be a list of
path (or path segments of the same length. Note: the path must be
long enough to display the text or the text will be cropped by the svg
viewer.
:param font_size - a single float of list of floats.
:param openinbrowser - Set to True to automatically open the created
SVG in the user's default web browser.
:param timestamp - if True, then the a timestamp will be appended to
the output SVG's filename. This will fix issues with rapidly opening
multiple SVGs in your browser.
:param margin_size - The min margin (empty area framing the collection
of paths) size used for creating the canvas and background of the SVG.
: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.
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 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.
:param svg_attributes - a dictionary of attributes for output svg.
:param svgwrite_debug - This parameter turns on/off `svgwrite`'s
debugging mode. By default svgwrite_debug=False. This increases
speed and also prevents `svgwrite` from raising of an error when not
all `svg_attributes` key-value pairs are understood.
:param paths2Drawing - If true, an `svgwrite.Drawing` object is
returned and no file is written. This `Drawing` can later be saved
using the `svgwrite.Drawing.save()` method.
NOTES:
* The `svg_attributes` parameter will override any other conflicting
settings.
* Any `extra` parameters that `svgwrite.Drawing()` accepts can be
controlled by passing them in through `svg_attributes`.
* The unit of length here is assumed to be pixels in all variables.
* If this function is used multiple times in quick succession to
display multiple SVGs (all using the default filename), the
svgviewer/browser will likely fail to load some of the SVGs in time.
To fix this, use the timestamp attribute, or give the files unique
names, or use a pause command (e.g. time.sleep(1)) between uses.
