Statistical charts have a fundamental role in the transmission and simplification of information, to the point that they can be considered in themselves an assistive technology, a type of cognitive accessibility through which we can use our visual system to reduce the effort that involves interpreting tabular data. For this reason, it is important that people with disabilities can access statistical charts on equal terms. Among visual disabilities, low vision stands out due to its high prevalence. Low vision is a visual condition that implies a substantial reduction in the sense of sight that cannot be corrected with corrective lenses, pharmacotherapy, or surgery, and that significantly impacts the daily activities of people who present it. The main objective of this thesis is to identify good and bad practices, as well as to systematize elements and characteristics that can facilitate or hinder the access of people with low vision to statistical charts. From this analysis, a list of heuristic indicators is developed for the evaluation of these elements. The list of indicators was validated through its application in three studies: charts from national and international digital newspapers, library and information science journals, and a final set of charts published by governments and non-governmental organizations in the context of the communication of the pandemic caused by Covid-19.
