Identify this graph of data points through which a line of best fit is often drawn.
One type of this visualization method checks for publication bias and is supposed to look like a triangle. In addition to that type, called a "funnel", another type—which shows random noise when a correct model has been chosen—uses the residual as the dependent variable. This can be used to select a type of smoothing spline or regression curve, and it can also be used to approximate the correlation coefficient before that value is calculated.
