The photo shows a map of Poland. The Vistula River is marked in blue running through the center. I would like you to make the following modifications: 1) The shape of the country MUST remain exactly the same, 1:1. 2) The only thing I want you to change is to replace the blue line with a bicycle chain, which should contain exactly 120 links from south to north. It MUST follow the EXACT path of the current blue line.
