Qt Creator is a developer's code editor. It does not include a version of Qt against which you develop, or a C++ compiler. (Just like Eclipse does not include a JDK, or VS Code a C# compiler)

Qt Quick is a standard component of the Qt C++ library

There are Qt add-ons (Qt Charts, Qt Data Visualization) for charting which may be useful. These can be accessed from Qt Maintenance tool installed with your Qt Library.

What access you have to various components of Qt from a Python environment will depend on that environment. PyQt5 seems to have both add-ons.
