This is a simple comparison between Polars and Pandas as used in a Plotly Dash App.

App Preview

Here's a preview of the app: Demo: https://dash-polars-pandas-docker.onrender.com/

Note: The app is hosted for free, so it might take a few seconds to load.

Introduction

This app includes 3 main pages:

1. Speed Comparison: An interactive speed comparison between Polars and Pandas. This is not fully optimized or a true benchmark, but it gives a rough idea of the speed difference between the two libraries.
2. Polars Dash Recipes: A collection of recipes for using Polars in Dash. The main idea is to explore syntax differences that might be helpful for someone transitioning from Pandas to Polars.
3. Minimal Dash App (in Polars): This example is from the Dash documentation, rewritten with Polars instead of Pandas.
