Check out the journal article about OSMnx.
The heart of Allan Jacobs’ classic book on street-level urban form and design, Great Streets, features dozens of hand-drawn figure-ground diagrams in the style of Nolli maps. Each depicts one square mile of a city’s street network. Drawing these cities at the same scale provides a revealing spatial objectivity in visually comparing their street networks and urban forms.
We can recreate these visualizations automatically with Python and the OSMnx package, which I developed as part of my dissertation. With OSMnx we can download a street network from OpenStreetMap for anywhere in the world in just one line of code. Here are the square-mile diagrams of Portland, San Francisco, Irvine, and Rome created and plotted automatically by OSMnx:

Western Europe gets all the attention, but that means it also gets all the tourists. Here are some of my favorite old cities that I’ve visited on the other side of the continent, along with a few photos I took while there. Granted, a few of these places are now squarely on the backpacker circuit, but many remain underexplored. What they all share is an incredible, exhilarating sense of urbanism — old and new.
Eastern Europe itself is hard to define. Competing designations might include only the former Soviet states, or all the formerly communist European nations.

Here I will play fast and loose with the geographic boundaries: these are just cities somewhere vaguely toward the eastern side of the continent. Apologies to any readers whose country is usually considered a part of Central or Southern Europe.
First up: Mostar. A small city in the south of Bosnia and Herzegovina, Mostar is most famous for its medieval Ottoman center and its Old Bridge, or Stari Most:
