title: Generate a SVG file from bunch of coordinates
body: <p>I have a text file containing a lot of rectangles defined by their 4 vertex coordinates in x and y. Is there a way I can easily generate a SVG file that draws out all these rectangles so I can open it in a viewer like inkscape or even a browser to look at the arrangement. Ideally if the rectangles can be drawn with 50% transparency so I can see overlaps, that would be really great.</p>
  
  <p>Any help would be greatly appreciated.</p>
  
  <p>Thanks</p>
