 Lux is a Python library that makes data science easier by automating aspects of the data exploration process. Lux facilitate faster experimentation with data, even when the user does not have a clear idea of what they are looking for. Visualizations are displayed via [an interactive Jupyter widget](https://github.com/lux-org/lux-widget) to allow users to quickly browse through large collections of data directly within their Jupyter notebooks.
