The graph presents data on how many people were served in four different food chains: burger bar, chicken spot, Pizza Hut, and Donut Bro, from 1990 to 2015.
Overall, it can be seen that while Burger Bar and Donut Bro had the lowest figures in 1990, Pizza Hut and Chicken Spot had the highest figures in the same year. However, at the end of the given period, Donut Bro saw a significant rise and had the largest number of visitors in 2015.
Burger Bar remained stable for the first five years, from 1990 to 1995, with one thousand customers, then gradually climbed until 2015, when it reached under four thousand customers. Donut Bro experienced a dramatic surge during the two decades between 1995 and 2015, increasing from almost two thousand customers to eight thousand customers—the highest number in 2015.
On the other hand, Chicken Spot and Pizza Hut demonstrated a downward trend during the given period. In 1990, Pizza Hut served 8 thousand people, which was the peak in that year. Over 25 years, this number saw a gradual drop, decreasing to roughly 5 thousand. Chicken Spot recorded erratic changes. Between 1990 and 1995, there was a negligible fall. In the next ten years, it slightly fluctuated. From 2005 to 2015, this restaurant maintained the same level, with 3 thousand customers—which was half the number of customers in 1990.
