A binary tree image made in <a href="https://en.wikipedia.org/wiki/Adobe_Illustrator" class="extiw" title="w:Adobe Illustrator">Adobe Illustrator</a> based on the original source of <a href="//commons.wikimedia.org/wiki/File:Binary_tree.png" title="File:Binary tree.png">Binary tree.png</a>, to replace that image. This is much like <a href="//commons.wikimedia.org/wiki/File:Binary_search_tree.svg" title="File:Binary search tree.svg">Binary search tree.svg</a>, but with the elements shuffled to avoid insinuating that binary trees have to be in order.
