Visualizing authors' production over time coupled with a variable of interest in mapping reviews
Year: 2026
Type: software
Abstract: This R script was developed to support mapping reviews and systematic mapping reviews by visualizing the most productive authors over time in relation to a researcher-defined classification variable. The workflow uses the Authors' Production over Time output generated by the bibliometrix package and allows researchers to incorporate an additional categorical variable of interest, such as taxonomic group, research focus, methodological approach, intervention type, or any other classification relevant to the study. The script summarizes the number of publications produced by each author per year and represents their distribution across categories using proportional pie charts. The size of each circle reflects the total number of publications by the author in a given year, while the colors represent the selected categories. Figures can be exported in SVG, PNG (600 dpi), and TIFF (600 dpi, LZW compression) formats, supporting both editable vector graphics and high-resolution outputs suitable for scientific publications. Researchers should replace the example dataset, classification variable, category labels, color palette, year range, and graphical parameters according to their mapping review. The workflow is implemented in R and primarily integrates data exported from bibliometrix with functions from packages including tidyverse, readxl, scatterpie, and ggplot2.
