This year for National Coffee Day (September 29), Redfin looked at the 100 largest cities that Walk Score and Redfin serve and found the top 10 with the most coffee shops per capita. We then stirred through the data to see how many of these coffee shops in each city are indie cafes versus large chains. (We defined large coffee chains as those with 30 or more retail locations.) The interactive visualization below shows the findings of the analysis on the top 10 cities, along with a map of coffee shops for each city. We also plotted all the locations of the largest coffee chains on a map. Read the full post here.
