# accessibility.description

A text description of the chart.

Note: Prefer using linkedDescription or caption instead.

If the Accessibility module is loaded, this option is included by default as a long description of the chart in the hidden screen reader information region. When the Exporting module is also loaded, it is embedded into exported SVGs as a Dublin Core RDF `<metadata>` block, so the description is preserved in downloaded images for indexers and machine readers. The embedded value falls back through linkedDescription, caption.text, and finally the generated chart-type description.

Note: Since Highcharts now supports captions and linked descriptions, it is preferred to define the description using those methods, as a visible caption/description benefits all users. If the `accessibility.description` option is defined, the linked description is ignored, and the caption is hidden from screen reader users.
