Inthispaperwewillaskthequestionofwhatproficiency in a textual language (e.g. English) has in common with eval uating information visualizations. We admit that this ques tion might not seem completely straightforward. Therefore wewill first presenthowexperimentalpracticeledustothis question. We hypothesize that the ability to use a visual ization (to speak the visual language) affects both objective and subjective evaluation methods. We propose to transfer the use of language testing and grammar description from linguistics to human computer interaction evaluation.
