This report reflects the findings of a high-level assessment of Statista for its conformance with the W3C Web Content Accessibility Guidelines version 2.1 (WCAG 2.1).
There are very few WCAG 2.1 compliance issues with Statista, and the few that are present are programmatic in nature and should be relatively easy to fix. However, creating an accessible platform is a constantly moving goalpost, so it is important to keep in mind that there are continual updates to the WCAG standards that may require more work in the future. Below are the most critical issues to focus on correcting to improve access for all potential users of the system.
Top 3 Issues:
- Contrast: The biggest issue facing Statista is color contrast. Several color contrast issues were flagged by automatic analysis tools that should be further investigated. Many of these were confirmed on a manual analysis, and several color combinations that result in less than a 4.5:1 contrast ratio are listed below. Many of these issues will likely be solved by changing the color palette for these combinations, but a manual review will still be necessary to check text that is in front of an image or a gradient.
- Compatibility: There are several issues with compatibility. While these are relatively minor in most instances, some will need further investigation. For an in-depth guide to ARIA implementation, please see the WAI-ARIA Authoring Best Practices Guide from W3.
- Information and Relationships: Issues with labeling and information relationships were identified. This will need to be addressed in order to meet WCAG 2.1 AA compliance.
