gmap | GMap : Graph-to-Map visualization tool | Data Visualization library

How can I add lines segments between two points in a gmap using the rbokeh package.

For example, the code below draw the points but doesn't add the segments.

Google Maps JS API began displaying blue focus border around the map after switching to another browser tab and then go back. Once the map is clicked the border vanishes.
The element with the border is generated by Gmaps and within their DOM. Border seems to show only in full-page map display.

Tracing Gmap DOM show a border at child of gm-style: (div.gm-style > div)

Im having a Google Firestore collection called users which has the below format :

I have a line of code that looks like

I am creating an app for AppGallery using Huawei Map Kit. Map kit doesn't have a cluster manager, as Gmaps. You can only make markers clusterable, but there doesn't seem to be any way of handling that clustering, especially the onClick event.

Does anyone know a way that I can menage the on cluster click event? As of now, clicking on a cluster of markers procs a random marker click event.

I am more of a Java programmer and still somewhat new to development (2 years or so, can write Java code & web apps just fine) however the company I work for has 4 Rails applications and was asked to get this application working called CtrlPanel. I have been having to learn Ruby on Rails in order to help get this issue with this app fixed and get it working.

I have been working on this problem for over a week all day long every day and nothing I do is fixing it.

I fixed everything to the point the app comes up, web server runs serves the pages but all views are white screens as long as this application.html.haml file is present. I re-wrote the file with very basic bootstrap and it sort of works but nothing looks right. The problem seems to stem from 1 single like that simply says: = javascript_include_tag "application"

I have been all over the internet and have tried every single fix from changing coffee-script-source to v1.8.0 as I read Windows has an issue with newer rails and that file, I have tried every variation of changing it from application to default, and every type of ending you can think of no matter what I do it gives me this error message which I can not seem to find.

I am not even sure WHAT that line does, I assume it has to do with the new Google Maps API and I verified the key is valid and it was working before.

This is the error is it giving it says the line with "= javascript_include_tag" "application" giving error ExecJS::RuntimeError at / SyntaxError: [stdin]:1:1: unexpected //=

I am running a PC on Windows 10 20H2 x64 UEFI ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x64-mingw32] Rails 6.1.3

(I did also install Ubuntu on another machine and it gives the exact same error, also gives the same error on another Windows machine)

The app is working IF I delete the "application.html.haml" file and put in a skeleton basic version all of the other views start working but of course none of them look right no menus no bootstrap no nothing.
Here is the application.html.haml file.

Right now I am using vuetify and vue js to implement the map functionality in my application. I am using vue2-google-maps package to implement it and as of now it works fine for me.
