A line graph titled 'Average number of citations per year' displays data from 2016 to 2025. The x-axis represents the years, starting from 2016 and ending at 2025. The y-axis represents the number of citations, ranging from 2 to 10. The graph shows a steady increase in citations from 2016 to 2018, followed by a more significant rise until 2020. The peak occurs in 2021 with approximately 9 citations. After 2021, there is a sharp decline in citations, reaching around 5 in 2022. The number of citations then fluctuates slightly, with a minor peak around 2023 before dropping sharply again by 2025. All values are approximated.Average number of citations per year
