I love the maps that Karl at Great Circle Mapper (gcmap.com) makes available. Now I’ve made it easier to embed them in a blog post on WordPress. Added bonus: It automatically includes the links back to Karl’s site per the notes in the FAQ page. Simply install the (very lightweight) plugin and you get a new shortcode to use on your site: [gcmap]. Parameters are available to control the look and feel of the maps as part of the shortcode.
More details available on the <a href="http://blog.wandr.me/plugins/great-circle-mapper/" rel="nofollow ugc">plugin homepage</a>.
