Smoothed Stacked Area
amCharts 5 comes with a number of line smoothing algorithms that you can use to suit your particular data.
This demo also uses a grainy fill pattern. Grain pattern is a special kind of pattern that can complement regular fills with overhead pixel noise to add that additional fuzzy look. It works by applying a random assortment of semi-transparent dots over existing fills.
