sankey diagram python

A Sankey Diagram is a visualisation technique that allows to display flows. Several entities are represented by rectangles or text, and linked with arrow that have a width proportional to the importance of the flow. You are allowed to adjust the gap between nodes and the gap between the node and flow link for all plots together. Please use ide.geeksforgeeks.org, generate link and share the link here. Sankey diagrams are commonly used for purposes like population migration, website user journey, the flow of energy, the flow of other properties (oil, gas, etc. Sankey diagrams are a type of flow diagram in which the width of the arrows is comparative to the flow rate. As an example, you might start with 100% of a fuel’s energy on the left side of the diagram… I am impressed by the Sankey diagrams produced with ‘sankeypython’, a new open source project. The best way to get started is to use it in a Jupyter notebook (more advanced users can use it outside the notebook environment to export JSON/SVG but this is still under development; see this comment ). 1. Plotly is a Python library that is used to design graphs, especially interactive graphs. floWeaver is a Python package, but you can successfully use it as a data analysis tool even without too much familiarity with Python. Sankey Diagrams in Python. If you like GeeksforGeeks and would like to contribute, you can also write an article using contribute.geeksforgeeks.org or mail your article to contribute@geeksforgeeks.org. ), and many more.
