Eiffel Tower,Iconic landmark in Paris,Attraction,48.8584,2.2945,Landmarks
Le Louvre,Famous art museum,Museum,48.8606,2.3376,Museums
```

Each line in the CSV file represents a single POI, with the following fields:

- `name`: The name of the POI.
- `description`: A brief description of the POI.
- `category`: The category or type of the POI (e.g., Attraction, Restaurant, Hotel).
- `latitude`: The latitude coordinate of the POI.
- `longitude`: The longitude coordinate of the POI.
- `layer`: The layer in which the POI should be placed in Google My Maps.

By organizing your POI data in this structured format, you can easily manage and update your information using Vim or any text editor. You can also quickly filter, sort, and process your data using simple Linux commands or custom scripts.

Here's a step-by-step workflow to create and manage your POI data:

1. Create a new file named `travel_pois.csv` using Vim:

   ```
   vim travel_pois.csv
   ```

2. Add your POI data to the file, following the CSV structure mentioned above. Use Vim commands to edit and navigate the file efficiently.

3. Save the file and exit Vim.
