Animation of a SVG graph does not work

[marmarczak]

Dear Leonardo and users of jQuery DrawSVG,

first of all many thanks to Leonardo for providing this plugin! I would like to apply it to animate an SVG graph attached to this post (as SVG file in the folder GerIPI.zip). In my attempts to bring it to work, I added the code directly in the html document and tried the simplest code:
var $svg = $('svg').drawsvg();
$svg.drawsvg('animate');
However, this did not work. Maybe there is some problem with the SVG file (which I unfortunately cannot find) since an attempt with some simple manually entered SVG code was successful.

I would be very grateful if someone could give me any hint what could possibly go wrong while trying to animate my SVG graph. Many thanks in advance for your help!
