Why smooth the curve for this graph? Seems sloppy to me, and misleading. The costs fluctuate, depending on year, but the implied curve suggest logarithmic escalation, when that rate/pattern has not been proven yet. There are too many variables; corruption, economies, sponsorship, built infrastructure. It’s just the last few instances that jumped higher than previous years. Just plot the actual numbers, don’t try to plot a pretty curve for the sake of your impressions of what might happen. (Obviously, costs will rise, but don’t assume you’ll know by how much). A single graph can never tell the whole story anyway, but this just bugs me; seems like a Fox News kind of chart.
