B4J Code Snippet [PyBridge] [Server] Online charts with Plotly

Porting of this desktop example: https://www.b4x.com/android/forum/t...tion-of-hierarchical-data-with-plotly.167965/ to jServer.
PyBridge runs with a background worker and the interaction with this worker is done with CallSubDelayed. This ensures that the code will be executed with the correct thread.

Private Sub Btn_Click (Params As Map)
    Dim req As GraphRequest
    req.Initialize
    req.GraphType = Params.Get("target")
    If ValidTargets.Contains(req.GraphType) = False Then Return
    req.Callback = Me
    Result.SetHtml("Creating graph...")
    CallSubDelayed2(Main.PyWorker, "Show_Graph", req)
    Wait For Graph_Response (Html As String)
    Result.SetHtml(Html)
    ws.Flush
End Sub

See the dependencies in the desktop example. I recommend using a global Python runtime: https://www.b4x.com/android/forum/threads/pybridge-the-very-basics.165654/#post-1018942

Note that unlike with the desktop example, the generated html doesn't include the engine JavaScript. It is instead loaded as part of the page, making the generated html much smaller.
The example uses bootstrap and is mobile friendly.

just Wow... I think that we need a lot of "new" bootstrap examples, with many controls (jquery or newer)... with simple intergration
that will help us create PWA server-apps with nice frontend !
