What could A and B represent

Imani is excited she has been working on her 4th year thesis project focused on food security and children's health, and the data has been yielding some very interesting ndings. For many years, Gritsburg had been a struggling neighbourhood in the large metropolitan city of Gourmandeville due to years of economic downturns and the decline of the manufacturing sector. Public health officials had expressed concern about how challenging it was for Gritsburg residents to access healthy foods, as the only places to buy food in the community itself were fast-food outlets, pubs selling mainly burgers-and-fries type of fare, and corner stores were stocked with chips, candies, doughnuts, ice cream and confectionary. In addition, there was very little public green space in the neighbourhood, and the few facilities that did exist were poorly maintained. Gritsburg residents had lobbied the Gourmandeville City Council to invest in the neighbourhood with little success. A few years ago, a multi-national corporation convinced the council to allow them to build luxury condominiums and associated upscale eateries and shopping in Gritsburg, gentrifying the area, resulting in numerous evictions and rendering it unaffordable for many long-time residents.

She's selecting some data to feature on her poster for Thesis Poster Day, and has misplaced the figure legend that goes with this graph. She'll have to go back to her notes to remind herself what 'A' and '3' indicate. what do you think 'A' and '3' could be, and what would your interpretation of the data be in that case
