Concerns: ASCII diagrams depicting quantum circuits are unwieldy and not useful for larger circuits.

• Allow control over the level of detail that is rendered on ASCII diagrams (e.g., for Kraus operations).
• Support slicing of circuit diagrams to selected qubits only.
• Implement visualization with an ability to zoom in/out of circuit details.
• Support styling by operation tags and tag regular expressions.
• Support generation of publication-quality figures with QPIC.
