IE 8 Support

From the support page it appears GoJs diagrams do not support IE below version 9.

However, Is there any possibility of making it work on <IE 9 ? I tried loading excanvas.js and using es5 shim sham scripts, but still not able to remove all the errors in gojs.js

The Javascript interpreter built into IE8 does not support many modern features, especially properties.
It is also vastly slower than all of the other browsers (including IE9), which would not help the experience.

So the only good solution for IE < 9 is to install Google Chrome Frame.

Thank you very much for quick help…
