When it comes to complex graphs and tables, accessibility is key to ensuring that all students, regardless of their access needs, can engage with their learning materials. We’ve covered the importance of alt text on the blog, but complex images tend to require a more comprehensive approach that may include design, as well as descriptions in text.
Our new resource collection, Accessible practice for maths and diagrams, contains helpful advice and guides for an accessible approach. In this post, we’ll start you off with three essential considerations to keep in mind when creating accessible graphs, charts and diagrams.
1. Use colour, patterns and text
When designing graphs, charts, and diagrams, it is crucial to prioritize inclusivity by utilising a variety of visual cues beyond just colour. High-contrast graphs that incorporate patterns and labels can benefit students with colour vision deficiency or low vision. By providing multiple layers of visual information, you ensure that all students can engage with the content effectively.
2. Use alternative text and image description
For students who are blind or visually impaired and rely on screen readers to access digital content, meaningful alternative text is essential. By crafting meaningful alternative text and adding image descriptions where necessary, you provide invaluable context and information about the content of the graph. This ensures that all students can fully comprehend the significance of the visual data being presented.
3. Show the data in a table
Incorporating data tables alongside graphs and charts significantly enhances accessibility for users of assistive technologies, such as screen readers. Unlike graphical representations, tables offer a structured and linear format that is easily interpreted by these tools. Additionally, students with cognitive or learning disabilities may find tabular formats more intuitive and easier to digest than graphs. By providing alternative formats, you empower a broader range of students to access and engage with the information.
Keeping your classroom inclusive
Prioritising accessibility for all types of images is not only a matter of compliance, but also a fundamental aspect of creating an inclusive learning environment. Take a look at our accessibility resource collections to learn more about ensuring your classroom is inclusive.
