As far as I can see all the embed codes are either JS or iFrame, so if you are hosted on wordpress.com you will need to use something like this http://shongjog.wordpress.com/2011/01/25/how-to-embed-iframe-widgets-in-a-wordpress-com-blog-%C2%A9-netty-gritty/
Scroll down to where it says "Extracting the frame url from your iframe widget code"
There's a fair bit to do but it does work I have it for a map which was an iFrame. On my blog here http://ukukee.wordpress.com/ukulele-map/
Hope this helps
