chartability skip to main content chartability what is chartability get the workbook get help learn more support us credits what is chartability chartability is a set of heuristics testable questions for ensuring that data visualizations systems and interfaces are accessible chartability is organized into principles with testable criteria and focused on creating an outcome that is an inclusive data experience for people with disabilities chartability can help you find accessibility barriers in data visualizations being able to recognize which parts of a data visualization produce barriers for people with disabilities can be tough but chartability has compiled existing standards research and community best practices into a comprehensive set of things to look out for ideally it can help folks who create visualizations really think deeply about accessibility when they design an example showing a perceivable test a low contrast chart left is being compared to a higher contrast version of itself right a dropper tool is used alongside a contrast calculator showing that the chart on the left doesn t have enough contrast what is accessibility accessibility also sometimes abbreviated as a11y is the practice of ensuring that as many people as possible can use understand and have access to a technology infrastructure tool product or service what is data visualization data visualization also sometimes abbreviated as dataviz or datavis is presenting data in a structured symbolic way the structure and semantics go beyond the visual however so we prefer to call these data experiences with the massive rise in data driven journalism the ease and availability of charting and analytical solutions and data s near ubiquitous appearance in public life more thorough and robust accessibility considerations are overdue chartability s principles chartability is organized into 7 principles 4 common to the accessibility space perceivable operable understandable and robust pour plus 3 more that extend from robust compromising assistive flexible caf these seven principles are used to focus explicitly on inclusive data experiences and the specific considerations produced by these challenging environments why use chartability chartability helps the design of data experiences stick to standards first before venturing into novel uncharted territory chartability is meant to be easy to get started with a shortlist of 14 tests that can be conducted in 20 40 minutes depending on the tester s experience but chartability s full test suite is also incredibly robust 50 heuristics total and can integrate well into proper auditing work of complex systems get the workbook the workbook for the latest version of chartability lives at this link which is always kept up to date currently we also have a downloadable microsoft word version of chartability s workbook which should remain up to date with the online version these workbooks are maintained from our single source of truth at our pour caf github repo that repo is also the place where we encourage community members to get involved and give feedback the workbook contains some very general information as well as a brief section on how to perform a quick style of audit using chartability note that chartability is a flexible material and is intended to assist professional auditors and teams or individuals looking to evaluate their own work as they go in our own work on the professional side of the spectrum we use chartability to generate audit reports that generally take weeks of work and have between 100 and 200 pages of documented evidence steps for reproduction and recommendations for remediation in our own work using chartability for a quick style of audit it is generally just a set of heuristics we keep in mind that add anywhere between 30 minutes and 2 hours of additional work on any given project auditing is for everyone because we have seen chartability used effectively by individuals evaluating their own work we highly recommend that every data visualization practitioner at the bare minimum learns to use chartability as they design and engineer it can be an immense time saver and significantly reduces accessibility barriers for a very small overhead of additional work but everyone even scientists data analysts designers and backend engineers can use chartability too we ve also seen it work in amazing ways as a common conversation tool and set of standards within teams learn more the best place to get started learning how to use chartability is within the workbook itself the workbook has a section how do you use chartability which provides an introduction to how someone might use chartability to evaluate the accessibility barriers in their own work but chartability is also something that can be integrated into larger auditing or research efforts as well for folks who might be trained accessibility analysts or researchers looking to improve the thoroughness and quality of their methods for example danyang fan and colleagues have a great research paper the accessibility of data visualizations on the web for screen reader users where they adapted chartability to suit their needs as part of a larger project using it alongside other research methods chartability s series on observable we have a series for chartability on observable that is slowly rolling out as we get extra time this is a collection of coding notebooks with live editable examples of data experiences that engage chartability at a deeper level this series primarily focuses on techniques for designing and engineering for accessibility not just auditing or evaluating it may not help you learn how to use chartability to evaluate visualizations but can be a great example of what data experiences that pass or fail are like and how to think more critically about the different aspects of their design research on the motivation and design process behind

screen reader users an academic project by fan et al that adapts and integrates chartability alongside their research methods general a11y data visualization resources the group dataviza11y maintains an excellent resources shortlist as well as a larger list of resources updated occasionally get help while chartability is very much the result of volunteer effort there are services that we can provide related to data visualization and accessibility training do you have a team and need some training building are you looking to build inclusive data experiences and need specialized engineers and designers auditing do you want confidence in knowing your team s charts and diagrams are accessible and want a professional external audit if you re interested in any of these services feel free to reach out to us at chartability fizz studio or call 1 919 932 9872 support us with enough support we could develop improvements training materials tools research and more there is already a lot of work being done in this space but we could use some help want to get involved nothing about us without us chartability has been vetted and tested by an array of people with disabilities including folks who are blind low vision have motor impairments cognitive disability autism vestibular disorders and adhd and color vision deficiency but even with all of that it still could use more community contributors the workbook s online website is intended as the central source of collaboration and has a github repo where community members can find out all the ways to get involved the goal is for chartability to grow into a community driven community centered piece of work credits and thanks chartability was created by frank elavsky and is licensed under the cc by sa creative commons
