nl4dv 0.0.4

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).

NL4DV

• Create Visualizations (Vis) in Python using Natural Language (NL)
• Add an NL interface to your existing Vis systems.

NL4DV stands for Natural Language toolkit for Data Visualization. It 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)
