I added a button to the custom map page so you can now get code to easily embed a map on your web page. You can take advantage of this feature by saving your map to a web page and then clicking the “Embed Map on Web Page” button.
This makes it even easier to extend your own web site with mapping capability. Let me know what you think of this new feature!
UPDATE: I removed the button from the saved maps page, but you will get emailed the embed code after creating your map. Just make sure you include your email address when creating your map.
