BuildAMol's built-in visualization leverages Plotly [? ] to generate interactive 3D representations of molecular structures. These visualizations can be customized with points, lines, annotations, and hover data to highlight specific features or regions of interest. While Plotly is the default option, BuildAMol offers additional visualization support using RDKit (2D only), Py3DMol , and NGLView , provided they are installed (Figure ). All visualization functionalities are conveniently accessible through methods of the Molecule class, minimizing the need for direct interaction with the Utils sub-package itself.
