Okun: Trade Networks

MapMaker Interactive from National Geographic allows you to annotate maps with your own lines, markers, text, shapes, links, etc.

• You can download and print these maps to use on your poster. 
• You can share the link to your map so that others can work on it (probably not at the same time though).
• You can select different "Base Maps" such as topographical or ocean maps, which remove current country borders and names.
