First phase the assignment idea:

The first task is to find a dataset and identify a business problem or a series of interesting questions. You must analyze and visualize real-world data. In order for you to have the greatest chance of success with the final outcome, it is important that you choose a manageable dataset.

2. To assist you in choosing a feasible problem and dataset, check with me by email about your idea for approval by 04/12/2022.

3. Informal discussions with the professor can help to refine the assignment.

4. Here are some links you can check to get data (but not limited to, so you can still do your search and find a dataset):
