Colorful path visuals help people see multiplicity. They also imply precision that models rarely possess. If you use spectral metaphors, pair every visual with a plain-language uncertainty caption. Captions should be mandatory, not optional.
Avoid animating credit flowing like liquid unless the underlying model is literally continuous—discrete models should look discrete. Mismatch between visual grammar and math grammar erodes trust faster than a boring table.
Teach teams to ask: "What would this chart look like if we doubled the path depth cutoff?" If the answer is "unrecognizably different," the chart is decorative. Decorative charts belong in marketing of marketing, not in operational reviews.
