## Abstract
High-quality visualizations are essential for exploring and communicating astronomical data, yet building complex and highly customized plots can be time-consuming. This presentation introduces CACHAI (Custom Axes and CHarts Advanced Interface), a Python package designed to simplify the creation of unusual scientific figures while preserving full flexibility and publication-ready control.
I will give a brief overview of how to install CACHAI, its main modules, and its design philosophy. The talk will then focus on two visualization tools currently implemented in the package: "Chord Diagrams", offer intuitive visualizations of correlations between parameters, we will see the basic usage, customization options, and real applications using chemo-dynamic data from Dantas et al. (2025). "Michinoff Faces", an ongoing work, encode multivariate data into expressive cat-like facial features. How would 3I/ATLAS look if it were a cat? We will see a demonstration of Michinoff Faces using published parameters for the interstellar objects 1I/ʻOumuamua, 2I/Borisov, and 3I/ATLAS.
