I am visualizing a Network with undirected links via Holoviews' Chord Diagram. Unfortunately, I can't find any option to choose a colour gradient for edges/links (to visualize that connections don't have directionality). Is there a solution or workaround for this?

This question is a followup to ggraph make filled arrow edges appear in legend (solved), but now I would like to add dynamic tooltips to the nodes to be able to show more information than can be done in a static image.
All the data, what I've tried so far & my R code is in this Rpubs document: https://rpubs.com/friendly/EDA-network
The script can be downloaded with the "code </>" button: https://rstudio-pubs-static.s3.amazonaws.com/912944_f40ed4eb53a242268ef57b7329d21d64.html#
Here is the network diagram I created using igraph and ggraph:
I tried using plotly::ggplotly() but most of the geoms used by ggraph are not recognized by ggplotly and all I got were points.
Here is a mockup of what I'd like to create showing a textbox tooltip when I hover over a node.
Can someone suggest either (a) how I can do this using the ggraph plot as a base or (b) a different network diagram package that could work.
As I have asked in the this question, I'm trying to plot curves varying according to different quantities, and I am mapping these quantities to the color and shape aesthetics.
However, when I do that, the dots having triangle shape look more transparent than the circular dots.
How can I solve this issue?
PS: I'm using the same code & dataset I have given in the linked question.
I'm drawing graphs using ggraph that uses layout functions from igraph package. However, the layouts I get are not entirely visually pleasing. In particular I have a graph with very strong connected components and some unconnected nodes. The result looks like this below:
So the nodes in the connected component are so close together that the edges are not even visible. Right now this used the fr layout, but other layouts give similar results. I seem to be unable to find a parameter that would loosen the graph up a bit that the connected component would not look like such a ball. Would be grateful for any suggestions.
I'm looking to create very high quality data visualization in R and I'm not sure how to create some of the gradient colors in the in the bar graph below (full link here).
I believe ggplot can do some gradient fills, but in this case, i'd need a stacked color and background color, both of a light grey-to-orange gradient. I can't find a command to do that. The column widths would have to be full and a dark grey border. (i don't need the symbols).
What ggplot (or other) command could replicate this design? Thanks for any direction. Really hoping I can recreate some of my favorite designs in R.
I want to do different color edges in polygon star. How do I this? I prepared easy sample for you in Print. That's here :

Just a guess, but what if you convert the star to curves, break the curve apart and color each side separately? Then you could group the separate curves to move/scale them together.
