Visual Autocompletion for Geospatial Queries

A method provides visual analysis of datasets. A user selects a data source. In response, the system presents a natural language interface for analysis of data in the data source and presents a map widget for selecting geospatial data points from the data source. A user provides a first user input to specify an incomplete natural language command directed to the data source and provides a second user input to select a region in the map widget. In response to the first user input and the second user input, the system generates and displays a map data visualization according to the first user input and the second user input, including a linguistic description of data points in the selected region. The system continues to display the selected region in the map widget. The map widget is configured to update the data visualization according to user modification of the selected region.
