PDF documents with diagrams are widely used to give users a visual experience. Hence, it is crucial to consider whether these documents are accessible to people with visual impairments. According to the eleventh revision of the International Classification of Diseases (ICD-11), there are two groups of visual impairments — distance visual impairment with mild, moderate, and severe blindness, and near-vision impairment who have difficulty with close vision tasks such as reading.
It is worth noting that roughly 2.2 billion individuals worldwide suffer from vision impairments. Consequently, it is crucial to include accessible diagrams and charts in PDF documents to ensure data is accessible to all users, regardless of any disability they may have. By following a few simple steps and adhering to the Americans with Disabilities Act (ADA) guidelines, it is possible to create diagrams, charts, and graphs that align with accessibility standards and enhance the reading experience for everyone. In this article, we will explore the process of remediating PDF documents with diagrams to make them more accessible to all users.
Verify Diagram Accessibility with Accessibility Checker
Ensuring the accessibility of a PDF document with diagrams is crucial before publishing it. An in-built PDF accessibility checker tool can aid in identifying accessibility issues with your document, including diagrams, graphs, and charts. The tool’s primary function is to verify if the diagram is accessible and highlight potential problems hindering accessibility for individuals with disabilities. Additionally, the tool explains the issue and offers suggestions for addressing and resolving it.
Include Accessible Hyperlink Text in Your Content
Incorporating descriptive link text is crucial when adding hyperlinks to your diagrams and charts, as it ensures that users receive clear and accurate information about the destination page. By doing so, individuals who use screen readers can easily navigate your document, significantly enhancing its overall accessibility. Rather than relying on generic terms such as “Click here,” “Go here,” or “Learn more,” it is best to use the full-page title as the hyperlink text. This approach lets screen reader users grasp the link’s context and navigate your document effectively. As a result, users of all abilities can enjoy a seamless reading experience when accessing your PDF document with diagrams.
Summarize the Key Points in your Takeaway Title
Before creating a chart, it’s best to summarize the key points in the title to make it more effective. The title should be specific, straightforward, and focused on a particular topic of the provided data. An assertive title ensures users understand the key issues highlighted in the chart, making it easier to take away important information. By adopting this approach, you can create a chart that effectively communicates the data to your audience while enhancing accessibility for all users.
Compose Alt-Text and Image Descriptions to Enhance Diagram Accessibility
When dealing with complex communication that must be conveyed to individuals with disabilities, it is essential to explore different accessibility options. One such option is to add alt-text to graphs, shapes, and diagrams, enabling users with visual impairments to understand the content of diagrams and charts. To ensure maximum accessibility, keeping the alt-text concise and accurately describing the graph or chart’s purpose and scope is crucial. By incorporating alt-text for graphs and diagrams and image descriptions, users with disabilities can effectively comprehend the information in the diagram, enhancing the overall reading experience.
Adhere to Color Contrast Guidelines to Improve Visibility
Incorporating appropriate color contrast guidelines, such as the Web Content Accessibility Guidelines (WCAG), is essential for creating diagrams and charts that are accessible to users with color blindness or low vision. Adhering to these guidelines ensures that the text and data are distinct from the background, improving visibility for users with different visual abilities. The two most commonly used color contrast levels are AA (minimum contrast) and AAA (enhanced contrast).
Level AA’s required contrast ratio is at least 4.5:1 for standard text and 3:1 for large text. Graphics and user interface components, on the other hand, require a contrast ratio of at least 3:1, according to WCAG 2.1. Level AAA demands a contrast ratio of at least 7:1 for standard text and 4.5:1 for large text. By adhering to these color contrast guidelines, you can significantly improve the visibility of your diagrams and charts, making them more accessible to users with color blindness or low vision.
Opt for a Single-Hue Palette to Simplify the Design
When creating diagrams, it’s important to consider users with color blindness and ensure that the content remains accessible. If color is a critical element in your diagrams, a single-hue palette is recommended to ensure easy differentiation for low-vision users. It is also essential to avoid using red and green together, as they can be particularly challenging for individuals with deuteranopia or protanopia.
To enhance accessibility further, limiting the number of shades used in your diagrams is advisable. This ensures sufficient contrast between neighboring colors, making it easier for color-blind users to differentiate between them.
Include Non-color Elements for Added Accessibility
Incorporating non-color components such as patterns, textures, icons, dashed lines, and spacing between chart elements can significantly benefit individuals with visual impairments. These elements can enhance the distinction between various data points in your diagrams and charts, making them easier to interpret.
Ensure Keyboard-only Accessibility for All Users
When designing diagrams and charts, it is important to consider keyboard-only accessibility for individuals with visual impairments. This is because keyboard navigation is often the primary mode of interaction with the computer for these users. By keeping this in mind during the design process, you can ensure that your diagrams and charts are easily navigable for individuals who rely on keyboard navigation.
Prioritize Static Visualizations for Optimal Accessibility
When creating visualizations for individuals with visual impairments, static visualizations like bar charts or line graphs are typically easier to comprehend. It’s best to avoid using interactive or animated diagrams and charts, as they can be challenging for screen reader users to navigate. Opting for static visualizations can provide a better experience for keyboard and screen reader users.
Enhance The Screen Reader Experience with Thoughtful Design
When creating PDF documents with diagrams, it’s crucial to make them accessible for screen reader users. To achieve this, avoid using complex sentences or technical jargon and use simple and concise language instead. It’s also essential to present the data logically, making it easier for visually impaired individuals to comprehend the diagram quickly and clearly.
