• IamGrooot: Here they are writing custom methods for highlighting nodes. If you see vis documentation they have builtin method visOptions(highlightNearest = true) which we can make use of. I am able to achieve that with R. But with js no luck datastorm-open.github.io/visNetwork/options.html
• niiyeboah: It seems you are referring to this visNetwork R package which is a separate library built on top of vis.js. I have looked through the official vis-network docs and was not able to find a highlightNearest option. It seems that unfortunately to do this in JS, currently the only way is to use a custom method.
• IamGrooot: ahh ok. my bad. Thanks
