Build a Simple Pipeline

Task

Create a pipeline that first scales the data and then applies logistic regression.

Why It Matters

Pipelines prevent data leakage by ensuring preprocessing is fit only on training data. They also make your code cleaner and your workflow reproducible - essential for production ML systems where you need consistent preprocessing.
