IPython Sankey diagram widget

Display Sankey diagrams in IPython / Jupyter notebook using d3-sankey-diagram.

To install use pip:

$ pip install ipysankeywidget

Alternatively, to install using conda:

$ conda install -c conda-forge ipysankeywidget

For a development install, see DEVELOPING.md.

Tested in Firefox and Chrome. There have been reports that it's not working in Safari.

See the d3-sankey-diagram API docs: the attributes of the SankeyWidget are the same as the properties of the sankey object described there.

To change the figure size, use the ipywidgets Layout object:

layout = Layout(width="1000", height="1200")
SankeyWidget(links=data, layout=layout)

See notebooks in examples folder for usage examples. You can try these online using

Binder, or follow the links to static versions on nbviewer:

Expose d3-sankey-diagram nodePositions() option to allow for custom node layout.

You can now show link values as SVG text elements. Set linkLabelFormat to a d3-format string; links whose value is more than linkLabelMinWidth will have a label using that format.
Upgrade to d3-sankey-diagram version 0.7.3
ipysankeywidget can now be installed using conda (thanks to Ali Alsabbah #33)
Add a check for duplicate links (thanks to Remi Bois #23)

Add events for clicking on nodes and links: on_node_clicked and on_link_clicked. These replace the on_selected event.
