How can I highlight the entire path of a specific flow in a node visualization?

My goal is to create a visual representation of the data flow stream for a project, which is separated into layers. To achieve this, I need to draw edges for all connected nodes and highlight the nodes and edges for a specific flow from beginning to end when a node is selected. I'm open to using either Python or JS for the visualization library. However, when using pyvis in Python, I encountered difficulty altering the edges that get highlighted when a specific node is clicked. Is there a way to modify these highlighted edges within the code? Alternatively, I've come across p5.js, but am uncertain about any potential drawbacks. If anyone has experience with this library, please share your insights.

Yes, it is possible to modify the edges that get highlighted when a specific node is clicked in pyvis. You can use the selectConnectedEdges parameter to highlight the edges connected to a node when it is clicked. You can also use the hoverConnectedEdges parameter to highlight the edges connected to a node when it is hovered over. To make other edges invisible when a node is clicked, you can use the hideEdgesOnDrag parameter. Here's an example of how you can add a tooltip with the label if you hover over the edge: 
from pyvis.network import Network

g = Network()
g.add_node(0)
g.add_node(1)
g.add_edge(0, 1, value=5, title="42") # weight 42
g.show('nx.html')
You can also change the color of edges in pyvis by using the edge_color parameter. As for p5.js, it is a JavaScript library that is used for creative coding and interactive graphics. It has many features that make it ideal for creating visualizations and animations. However, it may not be as well-suited for network visualization as pyvis. I hope this helps! Let me know if you have any other questions.

For visualizing data flow stream and creating edges for connected nodes, you can use a JavaScript library like D3.js or Cytoscape.js. Both libraries have extensive documentation and examples to help you get started. Regarding pyvis, if you were unable to change the edges that light up when a certain node is clicked, you may want to check the library's documentation or reach out to the community for assistance. As for p5.js, it is a popular library for creative coding and visualizations. While all libraries may have their own limitations, p5.js is well-documented and has a large community, which can be helpful in troubleshooting any issues that arise. It is always recommended to thoroughly research and test any libraries before implementing them in your project.
