htmlwidgets | HTML Widgets for R | Widget library

Suppose the contents of my plumber.r file are as follows below. I can successfully test each endpoint by visiting the path using chrome and viewing the expected output except for the \plotly endpoint.

When visiting that in my browser (i.e., http://localhost:8000/plotly) I get "An exception error occurred". I am not using R Studio, I am launching this from an RGui session using

I am trying to reproduce this simple plotly graph that shows images on datapoint hover. The code is available here.

However, I am failing to reproduce it. This is what I have so far:

I am dealing with a big network (1k + nodes, 1M+ connections) and I would like to set a custom initial zoom, since the standard zoom only focusses a few nodes and takes a lot of time to achieve de aimed proportion (where I can see the whole network).

Here is my code:

I would like tiles generated from geom_tile() to open a hyperlink using ggplotly and htmlwidgets. There is already an answer for points on a scatter plot.

This is what I have so far:

I'm creating a sankey chart in R with networkD3::sankeyNetwork() with the below sample data and script. I want to show percentage besides the node label.

the sankey with full dataset i create has 8 layers. i just post piece of data in below code.

I would like to display a scaled-up popup image on mouseover or on-click event on an image displayed in the rhandsontable cell similar to as shown here in DT table.

I would like to display the popup image for the image displayed in the table created as shown below:

I am trying to have produce a shiny application in which a Sankey plot, produced using NetworkD3, dynamically produces x-node labels. I think this requires passing a reactive element to onRender, but I am not sure how to do this.

I see an answer here: How to add columnn titles in a Sankey chart networkD3, but this solves the dynamic naming by calling .text("Step " + (i + 1)); in the onRender function. My labels are not so generic that I can just iterate and paste (the example below uses simplified names).

Here is an example:

I am trying to display images in a rhandsontable. The images are of various sizes. I would like to normalize the display size of the images to a single size. In this regard, I need help with how to adjust the display size of the image in a rhandsontable.

I am using the following example code where click on the point opens a link:
