Accessibility is achieved in the bullet chart control through WAI-ARIA standard. The bullet chart features can be effectively accessed through assistive technologies such as screen readers.


WAI-ARIA (Accessibility Initiative – Accessible Rich Internet Applications) defines a way to increase the accessibility of web pages, dynamic content, and user interface components developed with AJAX, HTML, JavaScript, and related technologies. ARIA provides additional semantics to describe the role, state, and functionality of web components.

The following ARIA attributes are used in the bullet chart:

Element Default description
Title Reads the bullet chart's title
Legend Reads the range name
FeatureMeasure Bar Reads the target width and value height
