We recently merge two examples and the resulting example is shown here: https://scikit-learn.org/dev/auto_examples/linear_model/plot_lasso_lasso_lars_elasticnet_path.html

This example should be revisited where we should have more narrative in a tutorial-like style. Indeed, this example could explain in more details what is a regularization path and discuss the difference between Lasso and Lasso-LARS, and between Lasso and ElasticNet.

Some of the experiment are really closed to the one presented in this paper: https://hastie.su.domains/Papers/LARS/LeastAngle_2002.pdf
