**What it does**
This tool ouputs serveral machine learning visualization plots using Plotly, including 'feature_importances', 'learning curve', 'precison recall curve', 'roc_curve',  and 'number of featues vs. rfecv gridscores'. This tool also ouputs configuration diagram for a deep learning model using the Keras model JSON file as input.


**Feature importances**
