How to display pairplot?

Question

Python

Pairplot is not displayed for me, although I even tried to run the code from the official site.
data = pd.DataFrame(d.getCSV('boston.csv'))
sns.set(style="ticks", color_codes=True)
b.doPairplot(data)
def doPairplot(self, dataset):
sns.pairplot(dataset )
There are no errors, but nothing happens.
Nothing at all.
