Alluvial plot for Gender, Days in Hospital Bins and Age Bins, coloured by mortality. A patient has gender 0 (male) may pass through to the days in hospital, bin $(0,7]$ (less than a week in hospital) and also be in the age category $(60,70]$. These patients would be at high risk of mortality indicated by the red colour flowing through the plot. Additionally the age bind $(70,80]$ and $(80,90]$ also have a high risk of mortality for these patients. The size of the bars indicate the number of observations in each section, i.e. there appears to be slightly more males than females in the dataset.
