Maker of free games suggests how much to donate with fun visualization (opens in new tab)

Pretty funny that "Street Performer / Homeless" is expected to pay more than "Student / Teacher" (probably accurate, too).

I would like to see an A/B test with and without that chart to see what the difference in donation rates is. I think the chart probably helps, but always better to gather data right?

I hope for the sake of their wallets that people working at startups don't take this chart too seriously. Based on the job postings I've seen in the past 6 months an awful lot of people would be paying the "rock star" rates!

I think comparing with other products (coffee at Starbucks, burger at McDonalds etc.) might be more effective.

+1 for the reference to Edward Tufte/Charles Minard Napoleon map.
