This image describes how different <a href="https://en.wikipedia.org/wiki/Map_projection" class="extiw" title="en:Map projection">map projections</a> can create illusions. The image to the left is an <a href="https://en.wikipedia.org/wiki/Orthographic_projection_(cartography)" class="extiw" title="en:Orthographic projection (cartography)">orthographic projection</a> of the northern Atlantic Ocean and the image to the right is a <a href="https://en.wikipedia.org/wiki/Robinson_projection" class="extiw" title="en:Robinson projection">Robinson projection</a> of the same area. The red line on both images is an air route between <a href="https://en.wikipedia.org/wiki/Stockholm" class="extiw" title="en:Stockholm">Stockholm</a> and <a href="https://en.wikipedia.org/wiki/New_York" class="extiw" title="en:New York">New York</a>. The two lines are placed on the same coordinates but on the orthographic projection the line is straight and on the Robinson projection the line is bent.
