Check out these time-lapsed maps showing the growth of a retail chain from Flowing Data. Great visualization of the speed and location of new stores. Also shows the diffusion across the country.
Lets you see the data of Walmart from 1 store in 1962 to 4,393 in 2010.
Check out these visuals:
- Watch the Growth of Walmart and Sam’s Club
- Growth of Target – 1962-2008
- Growth of Costco – 1976-2010
The large dot for a new store with small dot for existing store creates a great view. The final map is a good approximation of the population distrubiton of the U.S.
