🕶️ A view of its UI (v.1.103.0 on my Linux PC), with the main menus at the top, the parameter area for the molecule to be modeled on the left, and the 3D model of the molecule on the main right, where the user can position atoms and bonds and navigate around them. 📚️ Avogadro is a libre and multi-platform molecular builder and visualization tool that is part of a software suite called Open Chemistry project. It can visualize properties such as molecular orbitals or electrostatic potentials and features an intuitive molecule builder. It can be used by end-users of the chemical industry and education. It can be extended with C ++ plugins or Python scripts, and integrates with online databases. An intuitive and ergonomic tool. Excellent.
