Data Visualizer

While dealing with large CSV files to understand the quality of the data, it is painful in the table view of pandas or Excel. So, I build this data-visualizer app.

It shows one entry at a time with syntax highlighting. I can choose which columns to see and pick entries randomly to better understand the quality/distribution of the data.

Install dependencies

Install node.js, yarn, python ≥ 3.6, and pip.

Then, to install node dependencies, run

yarn install

To install python dependencies, run

pip intall flask flask-cors pandas

Run The App

To run the app, first put your files in <dataset_dir>/<subdir>. The run

export DATASET_ROOT=<dataset_dir>
yarn serve

It will run the app on http://localhost:3000. Here you will have the option to select appropriate <subdir> and the files within.
