Jupyter Notebook Support For interactive work, as recently became popular in chemistry , SpectraFit also provides a Jupyter Notebook interface. The Jupyter Notebook interface is based on the Jupyter Notebook package and supports the user with a graphical user interface (GUI) via Plotly. For those researchers and scientists who are interested in exploring the various benefits and use cases of this innovative interface, the SpectraFit Notebook class provides a reference Jupyter Notebook for a tutorial-style fitting procedure. This involves the crucial step of initializing both the data and description, which can be conveniently re-initialized through the `DescriptionAPI` class, as showcased in the Advanced Example I of the research paper.
