Do your charts ever look right but quietly use the wrong numbers?
I built Honest Chart, a free CSV→chart page that shows a SHA-256 fingerprint for the uploaded file alongside the chart. The idea is simple: if you’re making a slide or sharing a quick visualization, you can verify the source file hasn’t changed and the chart isn’t inventing numbers.

Would a visible file fingerprint make you more likely to trust a quick chart? Curious where this is useful—or where it falls short.
