👉 The term "axletree" is a concept in computer science and software engineering, often used to represent a tree-like structure of nodes or data. It is a type of graph that can be represented using adjacency lists (a.k.a. adjacency matrices) which are arrays of integers where each integer represents the number of edges between two nodes. The axletree is a data structure that allows for efficient querying and traversal of large graphs in various applications, such as data structures, computer networks, or
