What is it?

plotly.py is a Python graphing library for creating interactive charts. It is a high-level, declarative wrapper around plotly.js, which provides more than 30 chart types, including scientific, 3D, statistical, SVG map and financial charts.

The library offers two main interfaces: graph objects (plotly.graph_objects) for building figures trace by trace, and Plotly Express (plotly.express) for creating common charts in a single function call from dataframes. Figures render in Jupyter notebooks, marimo, standalone HTML files, and Dash applications.

Static image export is supported through the separate kaleido package, which requires Chrome or Chromium on the system. A Jupyter widget mode is available via anywidget.

Key features

  • 01Over 30 chart types, including 3D, statistical, map and financial charts.
  • 02Two APIs: graph objects for fine control and Plotly Express for quick charts from dataframes.
  • 03Interactive figures that render in Jupyter, marimo, standalone HTML and Dash apps.
  • 04Static image export through the kaleido package.
  • 05Jupyter widget support via anywidget.

Use cases

  • Exploring and visualizing dataframes in Jupyter notebooks.
  • Building interactive dashboards with Dash.
  • Producing shareable standalone HTML charts.
  • Creating scientific, 3D or financial plots from Python code.

Quick start

  1. 1

    Install plotly with pip

    pip install plotly
  2. 2

    Create a figure with graph objects and show it

  3. 3

    Optionally install Plotly Express extras

    pip install plotly[express]

Things to know

  • Plotly Express also needs a supported dataframe library installed separately.
  • Static image export requires Chrome or Chromium on the system.
