Embed Observable cells hosted on into Jupyter notebooks.

Project description


Embed cells from Observable notebooks into Jupyter notebooks.

View demo notebook on Colab

This library provides a simple way to embed cells and pass custom inputs values to them from Python code. For more complicated data flow in Jupyter notebooks, see the related library observable-jupyter-widget which uses the Jupyter Widget system to pass data back and forth between Python and JavaScript.


To install the library, import the embed function, and embed the "graphic" cell from this Observable notebook:

!pip install observable_jupyter
from observable_jupyter import embed
embed('@mbostock/epicyclic-gearing', cells=['graphic'], inputs={'speed': 0.2})

The simplest way to use embed() is to render an entire Observable notebook:


You may want to swap in your own data into a D3 chart:

import this
text = ''.join(this.d.get(l, l) for l in this.s)
embed('@d3/word-cloud', cells=['chart'], inputs={'source': text})

With multiple cells, you can embed interactive charts!

    cells=['vegaPetalsWidget', 'viewof sepalLengthLimits', 'viewof sepalWidthLimits'],

Embedding specific cells with the cell keyword parameter of embed([]) causes only these cells to be shown, but every cell still runs.

This behavior is slightly different than the Observable embed default.

About this library

This library uses the APIs provided by Observable to embed notebooks hosted on Observable in Jupyter.

The library was developed at Observable but is now maintained by Thomas Ballinger. All code added before Sept 2021 is copyright Observable.


See for an overview.

Because Python library includes JavaScript, you'll need node as well as Python to contribute to it.

The two JavaScript files included in an installed package iframe_bundle.js and wrapper_bundle.js are not saved in this repo. They are generated by rollup, a JavaScript "bundler" that combines JavaScript source code from files in the js folder and dependencies listed in js/package.json.

Installing the Python package with or pip install -e . will automatically run the bundler and produce these files.
