The shown bar graph depicts the quantities of travelers who spent time in each of two cities, Dover and Troy over four specific seasons. Overall, Dover attracts visitors better throughout the year, while Troy is busier with tourists in summer and fall, and quite quiet in other ones.
In Dover, the number of visitors has a significant increase in each of all seasons. At the beginning of the year, in spring, only 5000 tourists travel to the city which is the lowest number. However, the number of visitors abruptly surges which rockets doubly and triply at 10,000 and 15,000 people respectively in summer and fall, in comparison with the number in spring. Thereafter, the growth still continues that the winter is the busiest tourism season for Dover, welcoming 25,000 travelers.
In marked contrast, Troy does not have the steady climb throughout the year as Dover. Troy is busiest in welcoming visitors in summer which dominates first place with over 21,000 visitors. After that, the number in fall comes in turn with 20,000 tourists. Spring and winter are two unfavorable seasons for Troy that those numbers drop to the lowest number at around 5,000 visitors.
