Displaying graphical content in a webbrowser and interact like an app (Consulting)

I have a running app with vector graphics objects which can be individually clicked. The App is not a game, but should visualize the content at least with a Framerate of 2 per seconds when interacting.

Now I would like to port or run this app for using on a website. The app should be running in parallel with lots of sessions, because there will be lots of users using it in parallel.

I am not sure what is the best way to do with actual technologies in 2018.

• There are services, which let us run apps on theire servers. -> Not sure if this works properly and stable. I guess sessions are limited and costly.

• Converting the app into a Chrome app. -> Not sure if this works fine. What I saw is, that we need to install a special Plugin for Chrome, which I dont like the user to do.

• Creating an Applet ( old Scool ? ), which runs in a frame of an html page. -> Old scool, works different in different browsers. Security issues.

• Deploying an Java-Application to a Application-Server and creating vector graphics with HTML5 . -> Maybe slow.

Does someone have a hint, what technology to use ? Does Google offer something to show an apk in a browser ?
