What it is
Q-Q Plot graphs the quantiles of your data against the quantiles of a reference distribution. A straight line means "yes, this is normal" (or whatever you compared against). Anything else is worth investigating.
What it does
Sample quantiles vs theoretical (normal by default) with reference line, optional band, and tooltip.
Why use it
Histograms blur shape; a Q-Q plot says "normal or not" without a paragraph of stats.
Three ways teams use it
Quant
Returns normality check.
QA
Process output vs spec distribution.
Research
Pre-test of model residuals.
