Build Status


Dovex (Data overview, visualization and exploration) is a web-based tool to quickly provide an interactive overview and enable quick exploration of your dataset.

Use to identify columns of interest, explore correlations between inputs, and find problems in your input data.

Try it out by visiting

Local Installation

dovex has been tested on Python 3.

python -m venv venv
source venv/bin/activate
pip install -r requirements.txt


To run the software locally, first install the requirements above, then start the web server:


Next, visit and upload your data. The software expects the data to be in CSV or TSV format.

The first line should be column headings, followed by lines of data.

Running with Docker

The app has been packaged as a Docker container.

docker run -p 5000:5000 supernifty/dovex:latest

By default, the app stores uploaded datasets in the uploads directory. To persist uploaded datasets, use a mount point when starting the docker instance:

docker run -p 5000:5000 -v /your/upload/directory:/app/uploads supernifty/dovex:latest

Point your browser at to use the application.

Data types

Datatypes can be specified by starting the second line with '#'. Possible datatypes are: categorical, ordinal, numeric.

ordinal is currently unimplemented

Without specifying data types, the software will attempt to infer the datatype of each column.

Provided functionality

  • missing data by column
  • missing data by sample
  • explore input distributions
  • explore relationships between features
  • prediction


We have included the following public domain datasets:
