Good cheddar is expensive. I suspect this graph is very generous in what it considers cheddar.

Globally, the style and quality of cheeses labelled as cheddar varies greatly, with some processed cheeses packaged as "cheddar".¹

Processed cheese typically contains around 50–60% cheese and 40–50% other ingredients.²

It:'s also fundamentally a bit weird to compare the prices of these cheeses, as cheese prices tend to be extremely local in nature. What's a fancy foreign cheese in one place is just traditional food in another. And of course, price and quality varies a lot within each cheese. A lot of what is sold as mozzarella is also not recognizable as such in my opinion.
