The line chart illustrates how many pupils visited to Cardiff and Dublin from 2010 to 2020. That also measured to two lines and converted to millions of visitors in these periods.
Overall, the visitors have changes different ways for each period. Meanwhile, there is fall significant in Dublin visiting people. Moreover, there was suddenly peak at the last three years.
In terms of the Dublin, there was a decrease over four years and after rapidly rose of 3 million visitors at 2016. However, I figure that the visited substantially go down at the end of period by 2 million visitors.
In contrast, the blue line shows slightly increased for over five years. The following the three periods, that was reduced and there is rocked by follow until end of period of 5 million visitors.
Wrapping up, the both cities had different changes follow this period. Furthermore, the visitors of Cardiff would be an increase for upward trends for future.
