Platial.com Plugin/Widget?

Hi, I signed up for Platial.com recently and was looking forward to inserting maps into my blog posts. It sounded easy enough, but try as I might nothing will work. I’ve heard of a widget for Platial that is available through wordpress.com and I was wondering if it was also available to self-hosted blogs and if so, where. Alternatively, does anyone know how to insert the maps so they show up? Thanks!
