  Data visualization captions help readers understand the purpose of a
visualization and are crucial for individuals with visual impairments. The
prevalence of poor figure captions and the successful application of deep
learning approaches to image captioning motivate the use of similar techniques
for automated figure captioning. However, research in this field has been
stunted by the lack of suitable datasets. We introduce LineCap, a novel figure
captioning dataset of 3,528 figures, and we provide insights from curating this
dataset and using end-to-end deep learning models for automated figure
captioning.
