Visualize time spent per course

To help you best, I need a bit more context. Could you clarify:

1. Do you have data available (e.g., a table of courses and time spent)?

2. Do you want a chart or graph (e.g., bar chart, pie chart)?

3. What format is your data in (e.g., spreadsheet, plain text, JSON)?

4. Do you want a textual description, or are you asking for an image or code to generate the visualization?

Please provide the data or specify the format and preferences so I can generate the appropriate visualization.
