“…Most of these systems represent a chart in a hierarchical accessible tree from a top-level summary to axes and data values [GMS18, ZLL * 22, WOH * 15, FVL * 07]. For instance, the most recent system structurally divides chart content based on higherlevel encoding variables (e.g., positional axes and color legends) and lower-level individual data points, while the user can use arrow keys to navigate the hierarchy [BZS,ZLL * 22]. In addition to the structural navigation approach, another recent system demonstrated conversational interaction enabling blind people to inquire about the chart [SWM * 22].…”

“…Several studies provide insights on how the speech modality compares with tactile presentation [GMH10, WM18] and sonification [AAH14, SJJJ19]. While all these studies focus on understanding the broad experiences of typical blind people, researchers also studied the perspectives of blind scientists [CBF * 22] and accessibility experts [CPR * 22], struggles and expectations of visualization practitioners [JRG * 22,EBM22].…”

Modern visualization software and programming libraries have made data visualization construction easier for everyone. 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.
