If this Values, typically letters or numbers. is plotted onto a graph, this will be a time series graph, as it shows the frequencies over time.
From the graph, it can be seen that there is a large fluctuation each year in the amount of visitors. However, there is a pattern that repeats each year. For example, many more people visit in the summer months than they do in the winter months, and this is the same year by year.
