ARIA Charts are a set of guidelines designed to make charts and graphs accessible to people with disabilities. They provide a way to convey information visually while ensuring that screen readers and other assistive technologies can interpret the data accurately. This helps users who may have visual impairments to understand the content of the charts. These guidelines are part of the broader Accessible Rich Internet Applications (ARIA) specification, which aims to improve web accessibility. By following ARIA Charts standards, developers can create more inclusive web applications that allow all users to engage with data effectively, regardless of their abilities.
