  Natural language interfaces (NLIs) for data visualization are becoming
increasingly popular both in academic research and in commercial software. Yet,
there is a lack of empirical understanding of how people specify visualizations
through natural language. To bridge this gap, we conducted an online study with
102 participants. We showed participants a series of ten visualizations for a
given dataset and asked them to provide utterances they would pose to generate
the displayed charts. The curated list of utterances generated from the study
is provided below. This corpus of utterances can be used to evaluate existing
NLIs for data visualization as well as for creating new systems and models to
generate visualizations from natural language utterances.
