*1. Introduction to Time Series Data*

Time series data is a sequence of data points indexed in time order. These data points represent measurements taken at successive points in time. Examples include:

Stock prices
Temperature readings
Sales figures
Website traffic
Sensor readings

Time series analysis aims to understand patterns, trends, seasonality, and cyclical variations within the data to make predictions or gain insights.

*2. Setting up Your Environment*

Before we begin, ensure you have the following libraries installed. You can install them using pip:
