Topic on Extension talk:EasyTimeline/archive 2

I believe this extension has accessibility issues:

1. There doesn't appear to be a way to produce alternative text on a graphic created with this extension. And a large amount of data would not be suitable for alt text anyway.

2. The graphic data is not accessible to blind people. Depending on the amount of data, it may not be easy to use for mobile visitors either.

But...the data is all there. It's used to make the timeline.

Suggested resolution:

When generating a graphic timeline, also generate a text version, whether as a table or as a multi-level bulleted list. Automatically add a link to that text version, using visible link text in plain language, not the URL, below the image. Then add alt="" to the image tag.

Alternatively, add it as a collapsed section below the chart.

The advantage of generating the text version from the same data as the graphic is that there is a single source of truth and you do not risk them getting out of sync with each other.

Alternatively, add the data as a collapsed section immediately below the chart and labeled as "Chart data".

Yeah, you're right. EasyTimeline is legacy and doesn't support alt text. This is tracked in Phabricator somewhere, but since EasyTimeline has not been maintained for years it's probably not going to get done.
