Relationships between variables

The relationships between different variables can be visualized using the namespace plot from matplotlib. The scatter plot is used for visualizing relationships between two numerical variables, and the box plot is used for visualizing relationships between one numerical variable and one categorical variable. The complex conditional plot will be used to visualize many variables in a single visualization.

Scatter plot

To produce a scatter plot with pandas, all you have to do is to use the plot namespace. Within the plot namespace, you have a scatter() method and pass an x value and a y value:
