After reading on the section of micro/macro composition in Tufte's
Envisioning Information, I got really curious and did some research on it.
I found a definition for micro/macro reading on wikiviz sayng, "Micro-macro reading is a method for presenting large quantities of data at high densities in a way that a broad overview of the data is given and yet immense amount of detail is provided (Ruddle et al., 2002)."
But enough words. I researched for visual samples to get a better idea of the concept.
So here are the results (click on image to zoom in!):

I mostly found images of maps, which is convenient since the next project for class in information design is to redesign a map.
