Interactive multi-scale visualization of HIV using “Chameleon” for dynamic color coding of protein and atom properties: Zooming from an overview of the entire virus (a) to the capsid (b), the capsid interior (c), a single integrase protein in the capsid (d), and its atomic structure (e). Mind how protein colors become more differentiated as we zoom in (a–b), and how protein domains (c), secondary structures (d), and individual atoms (e) are being progressively revealed through dynamic color adaptations.
