What accessibility requirement pertains to infographics?

The requirement that text contrast for values in charts and long descriptions is critical for ensuring that infographics are accessible. This pertains to providing adequate contrast between text and background colors so that users with low vision or color blindness can perceive the information clearly. Additionally, long descriptions are needed for complex graphics where a simple label or alternate text may not sufficiently convey the content.

Enhanced contrast helps ensure that all users, including those with visual impairments, can access and understand the information being presented. It’s essential for infographics to communicate their messages effectively, which requires attention to how information is visually represented.

The other options do not address the core accessibility needs for infographics. Muted colors may not ensure accessibility; in fact, vibrant and high-contrast colors can be more effective if used correctly. While black and white graphics can simplify some designs, they can also limit the ability to convey information unless adequately supported with descriptive text. Lastly, while intuitive interactivity can enhance usability, it is not a fundamental requirement specific to the accessibility of infographics.
