This graph below provides information about both the actual and predicted number of visitors to Cardiff and Dublin from 2018 to 2040. Each line is shaped differently and uses a different color in order to clearly show the difference between the two lines.
To begin, it is clear that the visitors to Cardiff are higher in the last 22 years contrasting with visitors to Dublin, carrying a reduced amount and gradually decreasing. Therefore, both lines reach a peak, where they intercept with each other, each trend following an opposing direction. Furthermore, the country that garners the greatest amount of visitors would be Cardiff as it reaches a clear upward growth above the (approximate) 7 million point, while the amount of visitors to Dublin declines greatly in comparison to Cardiff, despite its brief rise between 2028 and 2030.
Overall, it is apparent that each line can be distiguished from the other, resulting in the viewing and comparison of the maximum number of visitors to each country.
