🧠 Real-Time Analogy:
Think of handling monthly sales data across 5 store branches.
📊 You use a pivot table to create a clean branch-wise monthly report (just like Excel).
But when sending the same to your machine learning model or dashboard tool — you need to melt the data back to long format.
It’s like folding clothes to stack them neatly (pivot) vs unfolding them to wash/sort (melt). 🧺📈
