Price level rankings for different goods and services categories in Europe and Central Asia

Ok, i read the description 4 times now and i am not shy to say that i dont understand what the graph shows or the description means to explain.

So, 10th on whatever means... 10th more expensive? 10th most cheapest? Is it cleared by income -meaning, is it relatove to median income of said country or is it just average proce based on dollar?

Too, what is the didfeeenxe between "price" and "price level"? For me thats the same (you can tell i dont undersrand the graph)

Thanks for explaining - and considering adapting the explanation.
