It would be great if Redash had options to add patterns to the bar and line chart visualizations.

Currently they are inaccessible to customers with visual impairments. I realize that labels can be added, but having the patterns would be a useful feature that all customers could benefit from. This feature could be added next to the color options.

Thank you for looking into this type of accessibility improvement!
