In search of food deserts

Très esthétique et assez efficace...
Last time I looked at where major grocery stores are across the United States. Where you shop for groceries changes depending on what region you live in, but hunger and nutrition carries less variance. It’s important that everyone has access to healthy food options, so I looked at the data, this time from Google and from a different angle. Instead of where stores are, I looked at how far away the nearest grocery store is.
The map above shows a sample of locations across the country, and line length represents distance to the nearest store. For example, in areas with a lot of lines headed to one spot is an area with fewer grocery stores. In contrast, mostly small line segments mean more grocery stores, and therefore less distance to travel to buy groceries.
