Challenge 3: Relational Plots

Understanding relationships between variables is essential in data analysis. A robust way to visualize these relationships is through relational plots. Seaborn, with its intricate API, provides an array of tools to showcase how variables interact with one another.

Relational plots in Seaborn can:

Identify patterns, correlations, and outliers among two variables.
Present the relationship between multiple variables across complex datasets.
Delineate data over time or other common variables using hue semantics.

By delving into Seaborn's relational plots, analysts can derive insights into multivariate relationships and how they evolve across parameters.

Task

Using Seaborn, visualize the relationships in a dataset:

Create a line plot to track changes in a variable over time or sequential order.
Display the relationship between two numeric variables with a scatter plot and differentiate data using color semantics.
