ACQUIRE THE DATA

The following code will read the dataset in directly from data.world.
You may need to join data.world, but I think it works without joining. (Joining is free.)

If you’d rather download and then import, here is the location of the dataset: https://data.world/data-hut/walmart-store-location-data
