NL4DV: Natural Language toolkit for Data Visualization

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.

Setup Instructions, API Documentation, and Examples

These can all be found on NL4DV's project website.
