Plotly is a library for creating interactive, publication-quality graphs in Python. It is an open-source library built on top of the popular JavaScript library D3.js. The library is free and easy to use, and it offers a wide range of features such as 3D plots, streaming graphs, and web-based dashboards.

To use Plotly in Python, you need to install the library using pip. You can do this by running the command “pip install plotly” in the terminal. Once the library is installed, you can import it into your Python script by using the following code:

import plotly.express as px

You can then use the library to create various types of graphs. For example, to create a simple line chart, you can use the following code:

data = [1,2,3,4,5]
fig = px.line(data)
fig.show()

This will create a simple line chart with the data provided. You can also customize the chart by adding labels, changing the color, and more.

Plotly also allows you to create interactive graphs, such as scatter plots and bar charts, that can be embedded in websites. To create an interactive graph, you can use the following code:

data = [1,2,3,4,5]
fig = px.scatter(data)
fig.show()

This will create an interactive scatter plot with the data provided. You can then customize the chart by adding labels, changing the color, and more.

Plotly is a powerful and easy-to-use library for creating interactive, publication-quality graphs in Python. With a few lines of code, you can create beautiful and interactive graphs that can be embedded in websites.
