Best Practices for Infographics:

When creating alt text for an infographic or charts, it's important to include key text, the overall context, and the layout of the image. For the infographic image, use the short description as the alt text to provide a brief overview. However, it is essential to include a long alt text below the image. This ensures that users can visualize the image and fully understand its content.
