using different data sets in pairplot for x and y code example

Example 1: seaborn pairplot

>>> import seaborn as sns; sns.set(style="ticks", color_codes=True)
>>> iris = sns.load_dataset("iris")
>>> g = sns.pairplot(iris)

Example 2: pairplot with selected field

pp = sns.pairplot(data=data,
                  x_vars=['age'],
                  y_vars=['weight', 'height', 'happiness'])
