Video, audio and interactive content

This can present barriers for some users, but can enhance accessibility for others. Some users may prefer to access data in a non text-based format. When presenting data in an interactive format (for example, SVG or Flash), provide the data being used to create the animation as a download file in CSV or XLS format. Give a description of the main points where possible. When using audio or video content, always provide a transcript. If the content is also on a third-party website, provide it there if possible. For example, on YouTube you should provide a transcript in the comments section.
