plots a dataframe as an alluvial plot. All numerical variables are scaled, centered and YeoJohnson transformed before binning. Plots all variables in the sequence as they appear in the dataframe until maximum number of values is reached.

Under the hood this function converts the wide format into long format. ggalluvial also offers a way to make alluvial plots directly from wide format tables but it does not allow individual colouring of the stratum segments. The tradeoff is that we can only order levels as a whole and not individually by variable, Thus if some variables have levels with the same name the order will be the same. If we want to change level order independently we have to assign unique level names first.
