Marco Russo and Alberto Ferrari explain when Sankey charts can actually make sense:
Picture this: you manage a company that sells subscription services on the web, and you want to track the evolution of your customers by analyzing different events to understand how many customers start a trial before they purchase or how many renew or cancel their subscriptions.
The report should look like this: the darker flow indicates the number of customers who skipped the trial and went directly from a phone call to purchasing a subscription.
