    Graphing is still necessary for the blind, but it’s more common to use a plastic sheet on a hard rubber clipboard with a stylus that causes the plastic to rise up when it’s pressed with a bit of force. (Though while googling for it I found plenty of examples like yours so maybe less common than I thought)
