How to Install Plotly in Python Step by Step

Plotly is a powerful library for creating interactive visualizations in Python. This guide will help you install it easily.

Prerequisites

Before installing Plotly, ensure you have Python installed. You can check using python --version in your terminal.

 
python --version

Python 3.9.7

If Python is not installed, download it from the official website. Also, ensure pip is up to date.
