Normal Quantile plot (Q-Q plot).
Plots distribution of the data against the expected normal distribution.

Expected values are straight diagonal line.
Overserved values are plotted as points.
Any deviation of the dots from the line represents deviation from normality.
Snake shaped dots wrapped around the line indicates deviation from normality.
Dots drift consistently below or above the diagonal line indicates Skewness.
Dots as S-shaped curve indicates Kurtosis.
