Load JSON data
Many open data portals make available JSONs datasets that are particularly easy to parse. They can be accessed directly via URL. Each object is a record, all objects have the same set of attributes, and none of the values are nested objects that themselves need to be parsed.
The New York City Department of Homeless Services Daily Report is such a dataset, containing years' worth of homeless shelter population counts. You can view it in the console before loading it to a dataframe with pandas's read_json() function.
