Automatically Visualize any dataset, any size with a single line of code.

AutoViz performs automatic visualization of any dataset with one line. Give any input file (CSV, txt or json) and AutoViz will visualize it.

To clone AutoViz, it's better to create a new environment, and install the required dependencies:

To install from PyPi:

conda create -n <your_env_name> python=3.7 anaconda
conda activate <your_env_name> # ON WINDOWS: `source activate <your_env_name>`
pip install autoviz

To install from source:

cd <AutoViz_Destination>
git clone [email protected]:AutoViML/AutoViz.git
# or download and unzip
conda create -n <your_env_name> python=3.7 anaconda
conda activate <your_env_name> # ON WINDOWS: `source activate <your_env_name>`
cd AutoViz
pip install -r requirements.txt


Read this Medium article to know how to use AutoViz.

In the AutoViz directory, open a Jupyter Notebook and use this line to instantiate the library

from autoviz.AutoViz_Class import AutoViz_Class

AV = AutoViz_Class()

Load a dataset (any CSV or text file) into a Pandas dataframe or give the name of the path and filename you want to visualize. If you don't have a filename, you can simply assign the filename argument "" (empty string).

Call AutoViz using the filename (or dataframe) along with the separator and the name of the target variable in the input. AutoViz will do the rest. You will see charts and plots on your screen.

filename = ""
sep = ","
dft = AV.AutoViz(

AV.AutoViz is the main plotting function in AV.


  • AutoViz will visualize any sized file using a statistically valid sample.
  • COMMA is assumed as default separator in file. But you can change it.
  • Assumes first row as header in file but you can change it.
  • verbose option
    • if 0, display minimal information but displays charts on your notebook
    • if 1, print extra information on the notebook and also display charts
    • if 2, will not display any charts, it will simply save them in your local machine under AutoViz_Plots directory



  • filename - Make sure that you give filename as empty string ("") if there is no filename associated with this data and you want to use a dataframe, then use dfte to give the name of the dataframe. Otherwise, fill in the file name and leave dfte as empty string. Only one of these two is needed to load the data set.
  • sep - this is the separator in the file. It can be comma, semi-colon or tab or any value that you see in your file that separates each column.
  • depVar - target variable in your dataset. You can leave it as empty string if you don't have a target variable in your data.
  • dfte - this is the input dataframe in case you want to load a pandas dataframe to plot charts. In that case, leave filename as an empty string.
  • header - the row number of the header row in your file. If it is the first row, then this must be zero.
  • verbose - it has 3 acceptable values: 0, 1 or 2. With zero, you get all charts but limited info. With 1 you get all charts and more info. With 2, you will not see any charts but they will be quietly generated and save in your local current directory under the AutoViz_Plots directory which will be created. Make sure you delete this folder periodically, otherwise, you will have lots of charts saved here if you used verbose=2 option a lot.
  • lowess - this option is very nice for small datasets where you can see regression lines for each pair of continuous variable against the target variable. Don't use this for large data sets (that is over 100,000 rows)
  • chart_format - this can be SVG, PNG or JPG. You will get charts generated and saved in this format if you used verbose=2 option. Very useful for generating charts and using them later.
  • max_rows_analyzed - limits the max number of rows that is used to display charts. If you have a very large data set with millions of rows, then use this option to limit the amount of time it takes to generate charts. We will take a statistically valid sample.
  • max_cols_analyzed - limits the number of continuous vars that can be analyzed
