Inspired by Nicola Rennie's brilliant work in the messy R package, this app brings controlled chaos to your data, helping you simulate real-world data challenges. Perfect for data scientists, educators, and developers who need to stress-test their pipelines or teach the art of data cleaning. Here is a tutorial on how to use chaos.
