+Figure 1 illustrates the distribution of accessibility violations across the 147 webpages in our dataset. 
+The results reveal that web accessibility issues are inherently multi-fault in nature. 
+Specifically, every webpage in the dataset contains more than one accessibility violation, and **85.03% of webpages exhibit at least 10 violations**. 
+Even under more stringent thresholds, a substantial proportion of webpages remain highly problematic: 68.03% of webpages contain more than 20 violations, 
+and over half of the webpages (55.78%) still have more than 30 violations.
+
+This trend persists for higher violation counts, with 31.29% of webpages containing more than 50 violations and 12.24% of webpages exceeding 100 violations. 
+Such a heavily skewed distribution indicates that accessibility defects are not isolated or sporadic, but instead co-occur extensively within individual webpages. 
+Consequently, repairing web accessibility in real-world systems typically requires addressing multiple, heterogeneous violations simultaneously, 
+rather than fixing a single defect in isolation.

 A11YBench covers 45 distinct accessibility violation types, corresponding to a broad subset of WCAG rules as identified by the IBM Accessibility Checker. 
 These violation types span multiple aspects of web accessibility, including missing or redundant alternative text, insufficient text contrast, improper ARIA usage, 
 non-unique landmark or navigation labels, and missing form or input labels.
 
-As illustrated in Figure 1, the distribution of violation types exhibits a highly skewed, long-tailed pattern. 
+As illustrated in Figure 2, the distribution of violation types exhibits a highly skewed, long-tailed pattern. 
 A small number of violation types—such as aria_content_in_landmark, svg_graphics_labelled, and text_contrast_sufficient—account for a substantial proportion of 
 all detected violations, while many other types occur less frequently. This observation highlights the uneven prevalence of accessibility issues across different 
 WCAG rules in real-world web pages.
