# Welcome to the Highcharts Gantt JS (gantt) Options Reference

# accessibility.typeDescription

A text description of the chart type.

If the Accessibility module is loaded, this will be included in the description of the chart in the screen reader information region.

Highcharts will by default attempt to guess the chart type, but for more complex charts it is recommended to specify this property for clarity.
