Accessing bounding box
Most tweets which have coordinate-level geographical information attached to them typically come in the form of a bounding box. Bounding boxes are a set of four longitudinal/latitudinal coordinates which denote a particular area in which the user can be located. The bounding box is located in the place value of the Twitter JSON.
The dataset has been loaded for you as a DataFrame in tweets_sotu.
