From the examples in this article, readers should find that these analysis methods are highly useful for chemists to quickly understand the characteristics and strengths of interactions of interest in an intuitive manner. As a result, computational chemists no longer need to constantly deal with large amounts of complex and abstract numerical data generated by theoretical calculations. The vivid images produced by these methods are also well-suited for inclusion in textbooks and undergraduate chemistry education, helping students gain a clearer understanding of interactions in various systems and fostering their interest in theoretical chemistry.
