The horizontal axis is marked with years from 2014 to 2024 in increments of 1 year. The vertical axis ranges from 0 to 40 in increments of 5 units. The graph shows eleven vertical bars and one curve. The curve begins at (2014, 2), dips slightly to (2015, 1), rises sharply to (2016, 14), gradually declines to (2017, 11), continues downward to (2018, 7), rises again to a local peak at (2020, 15), decreases to (2021, 10), continues to (2022, 8), drops further to (2023, 4), and ends at (2024, 3). The data for the bars are as follows: 2014: 2 publications. 2015: 1 publication. 2016: 4 publications. 2017: 9 publications. 2018: 13 publications. 2019: 1 publication. 2020: 11 publications. 2021: 11 publications. 2022: 14 publications. 2023: 24 publications. 2024: 36 publications.
