However, the extent of accessibility design they support for blind and low-vision people is relatively unknown. It is also unclear how they can improve chart content accessibility beyond conventional alternative text and data tables. To address these issues, we examined the current accessibility features in popular visualization tools, revealing limited support for the standard accessibility methods and scarce support for chart content exploration. Next, we investigate two promising accessibility approaches that provide off-the-shelf solutions for chart content accessibility: structured navigation and conversational interaction. We present a comparative evaluation study and discuss what to consider when incorporating them into visualization tools.Attribution 4.0 International LicenseCCS Concepts: Human-centered computing -> Empirical studies in visualization; Visualization systems and toolsHuman centered computingEmpirical studies in visualizationVisualization systems and tools10.1111/cgf.14833323-33513 pages
