title: Making an L-curve with sklearn's ridge regression
body: <p>A common way to visualize the solution of <a href="https://scikit-learn.org/stable/modules/generated/sklearn.linear_model.RidgeCV.html" rel="nofollow noreferrer">ridge regression</a> is an <a href="https://www.sintef.no/globalassets/project/evitameeting/2005/lcurve.pdf" rel="nofollow noreferrer">L curve</a> which plots the sum of squared errors against the ridge penalty for different choices of the regularization parameter. Is this possible to make with sklearn? </p>
