You'll use the **mall customers** dataset, which contains the following columns:

You should also follow these steps before clustering:
     
1.  **Load the data:** you'll use `pandas` to load the CSV file;
2.  **Select relevant features:** you'll focus on `'Annual Income (k$)'` and `'Spending Score (1-100)'` columns;
3.  **Data scaling (important for DBSCAN):** since DBSCAN uses distance calculations, it's crucial to scale features to have similar ranges. You can use `StandardScaler` for this purpose.

## Interpretation 

The code creates **5 clusters** in this case. It's important to analyze the resulting clusters to gain insights into **customer segmentation**. For example, you might find clusters representing: 

- High-income, high-spending customers;     

- High-income, low-spending customers;    

- Low-income, high-spending customers;     

- Low-income, low-spending customers; 

- Middle-income, middle-spending customers.
