Cover Story: ChatGPT drew a mental map according to the following information: “The campus is in a rectangular shape and its size is 2 km by 1 km. Inside the campus, the library sits at the very center. The student center is inside the campus and is located near the campus's southern boundary. The college is about a 5-minute walk west of the student center. A square-shape parking lot is located at the top-left corner of the campus, whose size (area) is about 1/8 of the campus. There are nine parking meters regularly distributed inside the parking lot, e.g., three rows by three columns. There is an EV charger next to each meter. The rectangular sports complex is at the bottom-right corner of the campus, whose size is 800 m by 400 m. The sports complex is divided into 4 fields: tennis, basketball, soccer and baseball. This gives rise to the question: how can we draw the above features in a map?” View this paper
