Dashed line in pysvg

I recently wrote a blog post on using pysvg to make a picture of chromsomes.

Now I wanted to figure out how to make a dashed line using pysvg.

The library seems to be missing a dedicated function for this, but I was able to do it with:

# define the dashed line style
    linestyle_dict = {'stroke-width':2, 'stroke':'black','stroke-dasharray': "5, 5"}
    linestyle = pysvg.builders.StyleBuilder(linestyle_dict)
    myline = shape_builder.createLine(0,0,300,300)
    myline.set_style(linestyle.getStyle())
    svg_document.addElement(myline)

If you want to change the lengths of the dashes you can change for example 'stroke-dasharray': "5, 5" to 'stroke-dasharray': "10, 10".
