Background data for: An analysis of bar chart usage in corpus data visualization

<p><b>Dataset description</b></p>
<p>This dataset contains information about the use of bar charts for corpus data presentation. It is based on a systematic review covering all papers (<i>n</i> = 1,183) published in five corpus-linguistic journals up to and including the year 2024 (<i>International Journal of Corpus Linguistics, Corpus Linguistics and Linguistic Theory, Corpora, Research in Corpus Linguistics, and the International Journal of Learner Corpus Research</i>). In total, the report pool includes <i>n</i> = 1,061 unique instances of bar charts, and the current dataset documents various properties of these diagrams, including information about their content (e.g. number and types of variables, number of levels per variable) and design (e.g. type of bar chart, scaling information, size, use of color). Further, information is provided about the frequency of use of different types of statistical graphs and statistical tables for each article (<i>n</i> = 1,183) in the report pool.</p>
