Which of the options below is a primary use of Jupyter Notebook?

Jupyter Notebook is primarily used for data analysis and visualization. It provides an interactive environment where users can write and execute code in various programming languages, particularly Python. This interactivity is crucial for data scientists and analysts because it allows them to iterate on their analyses quickly, visualize data in real time, and integrate rich media, such as plots and charts, within the same document as their code. The ability to combine code, text, and visual output facilitates a deeper understanding of data and enhances communication about findings, making Jupyter Notebook a popular tool in the fields of data science and AI.

The other options like database management, web development, and game development do not align with the primary functionalities of Jupyter Notebook, as it is not specifically designed for managing databases, creating web applications, or developing games. Instead, its focus is on data exploration and analysis.
