+## Visualization for External Systems 
+
+The `dataforge-vis` framework can be used to visualize geometry and events from external,
+non-Kotlin based systems, such as ROOT. This will require a plugin to convert data model
+of the external system to that of `dataforge-vis`. Performing such integration is a work 
+currently in progress.

+### Muon Monitor Visualization
+
+This directory contains a full-stack application example built with `dataforge-vis`.
+It is visualizing the 
+[Muon Monitor](http://npm.mipt.ru/projects/physics.html#mounMonitor) experiment set-up,
+including experiment's geometry and events (particle tracks).
+
+#### Reusing code and going Full-Stack with Kotlin Multiplatform
+
+The application includes both server back-end generating events, as well as client 
+visualization front-end.
+
+As is common for Kotlin multiplatform projects, the code base of this simple application 
+is put in the following main directories:
+* `commonMain` - common code, used by both JS client and JVM server. For example, the `Monitor`
+object describes general geometry definitions needed in all parts of the application.
+* `jsMain` - JavaScript client code. It performs visualization and reads events from the server.  
+* `jvmMain` - JVM server code. It runs `ktor` HTTP server, responding with event data when
+client requests them.
+
+Note that in a more traditional approach when client and server are developed separately
+and possibly using different languages, there would be no benefit of reusing common code.
