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.

Build this chart with AI
The prompt below can be used to build this chart with AI. For best coding results, use the most advanced AI models, like Claude Opus 4.6 and GPT-5.3-Codex. For more info and tips, check out amCharts AI docs.
Create a smoothed stacked area chart with three series (Cars, Motorcycles, Bicycles) for 2001-2012 using curved lines. Apply white borders with shadows on lines, a grain/noise texture overlay at low opacity on fills, and muted earth-tone colors (purples, grays, oranges). Include horizontal tooltips, XY cursor, pan/zoom, horizontal scrollbar, and entrance animation. Use amCharts 5 library.
