The vertical axis is labeled “Number of papers” and ranges from 0 to 60 in increments of 10 units. Four stacked vertical bars are shown for each year, representing “Augmentation”, “Automatization”, “Hybrid”, and “Unspecified”. A legend on the upper right identifies these categories. The data for the stacked bars on the graph are as follows: 2020: Augmentation: 2, Automatization: 0, Hybrid: 0, Unspecified: 0. 2021: Augmentation: 3, Automatization: 0, Hybrid: 0, Unspecified: 0. 2022: Augmentation: 3, Automatization: 2, Hybrid: 1, Unspecified: 0. 2023: Augmentation: 31, Automatization: 2, Hybrid: 1, Unspecified: 2. 2024: Augmentation: 38, Automatization: 15, Hybrid: 1, Unspecified: 4. 2025: Augmentation: 2, Automatization: 1, Hybrid: 1, Unspecified: 1.
