A classification system I built is going to go into production soon (it'll be part of a larger dashboard), and I'm looking for ways to better visualize and convey to business folks the results of a classification.Basically, given old data on which the model was trained, I predict the classes of new data, with the goal being to show whether the class distributions for the new data are statistically indifferent from the class distributions observed in the old data. So, if there are three classes A, B, and C in the old data, with proportions of 50%, 30%, and 20%, respectively, I compare the classification distribution for the new data with those original, observed proportions.Outside of a confusion matrix (which I think is probably inappropriate for most dashboard users), how else can I effectively present these results? I was thinking of a bar chart like this:
Visualizing results of a classification problem, excluding confusion matrices?

Here are a couple of options. I prefer the stacked column chart, which could also be annotated with the actual proportions if needed.
