Our previous interview study explores the needs and uses of diagrammatic information by the Blind and Low Vision (BLV) community, resulting in a framework called the Ladder of Diagram Access. The framework outlines five levels of information access when interacting with a diagram. In this paper, we connect this framework to include the global activity of sensemaking and discuss its (in)accessibility to the BLV demographic. We also discuss the integration of this framework into the sensemaking process and explore the current sensemaking practices and strategies employed by the BLV community, the challenges they face at different levels of the ladder, and potential solutions to enhance inclusivity towards a data-driven workforce.

翻译：我们之前的访谈研究探索了盲人和低视力（BLV）群体对图表化信息的需求与使用，由此构建了一个名为"图表访问阶梯"的框架。该框架描述了在交互图表时信息访问的五个层级。本文将此框架扩展至全局性信息解读活动，并探讨了BLV群体在此过程中面临的（不）可及性问题。我们进一步论述了该框架与信息解读过程的整合机制，系统研究了BLV群体当前采用的信息解读实践与策略、他们在不同阶梯层级面临的具体挑战，以及为促进数据驱动型工作力量包容性而提出的潜在解决方案。
