NL4DV is a Python toolkit that takes a natural language (NL) query about a given dataset as input and outputs a structured JSON object containing Data attributes, Analytic tasks, and Visualizations (Vega-Lite specifications).

Project description

NL4DV: Natural Language toolkit for Data Visualization

DOI:10.1109/TVCG.2020.3030418 arxiv badge PyPI license

NL4DV takes a natural language query about a given dataset as input and outputs a structured JSON object containing:

  • Data attributes,
  • Analytic tasks, and
  • Visualizations (Vega-Lite specifications)

With this output, developers can

  • Create visualizations in Python using natural language, and/or
  • Add a natural language interface to their existing visualization systems.
