Binary Tree Illustration with Red Node Connections

A clear visual representation of a binary tree data structure, illustrating its hierarchical organization. Each node, distinctly marked by a red circular outline, contains a numerical value. Gray lines connect the parent and child nodes, effectively showing the relationships and paths within the tree. The diagram also hints at the different levels or depths of the tree structure on the left side, making it a valuable example for understanding fundamental tree concepts in computer science.
