Hi kind contributors

Thank you for the easy to follow guide to setting up electron app. Everything worked fine for me in this course except for the bug with the polygon drawing package

I could kinda draw squiggly lines after following the tutorial, but my doodling disappeared the moment I release my mouse. Also, my browser buffer size increase as if there were more elements added to it, which I think is what the code below was trying to do:

var viz = new image('#visualization',null,[src],{hullAlgorithm:'convex'});

Because there was a code that was supposed to delete the original image and re-render it, the new image was taking super long to render while the old image was not deleted either. And the drawing didn't seem to be at the right location.

Please kindly help explain what was going on.

My entire code was:

var picture=require('cat-picture');
var image=require("lightning-image-poly");

var src=picture.src;
picture.remove();
var viz = new image('#visualization',null,[src],{hullAlgorithm:'convex'});

Thank you
