For the GeoJSON data collecting, I mainly collected two data. The first one os the shopping that I frequently go to, I include the nearest Macys, CVS near our academic building. For the second one, I marked all the CVS pharmacy I have visited.
I was motivated to do the second one because one day when I went to the CVS, which was supposed to be a 24 hr convenience store, it was closed. So I paid attention to the opening time and documented. Also, there are special centers within CVS, so I also documented the CVS special center.
