-# histoviewer
-Dynamic histograms for pandas DataFrames
+## Introduction
+Histoviewer is an interactive bokeh application for dynamically viewing histograms and bar charts for a pandas DataFrame input.
+
+Try out the application here (it may take up to a minute to start the heroku app):  
+https://histoviewer.herokuapp.com/sample_app
+
+Play around with the sliders, text inputs, dropdowns, and button widgets to update the data dynamically!
+
+## Features
+Histoviewer uses bokeh widgets to interact with the displayed plots. The column selection dropdown changes the data source to **df[column]**.
+
+- Continuous variables
+  - dynamically rebin histogram from 10-100 bins
+  - dynamically rescale minimum/maximum bounds of histogram
+- Categorical variables
+  - resort by y-axis (descending) or x-axis (alphabetical)
+  - reindex x-axis to filter categories
+
+## Getting Started
+To use Histoviewer, simply install the required dependencies:  
+```
+pip install -r requirements.txt
+```
+
+Then run the following code (in Jupyter notebook) to interact with a pandas DataFrame:
+```
+from histoviewer import histoviewer
+histoviewer(df)
+```
+
+For an example of how to run histoviewer from a python 2.7 script, see [sample_app.py](https://github.com/alvinthai/histoviewer/blob/master/sample_app.py).
