feat: Plotly Express iframes, DHC pydeephaven, envoy header fix

[mofojed]

• Updated dependencies and types to the latest versions
• Updated formatting
• Fixes #17, Tested by running the following snippet in a Jupyter lab and ensuring the plot appeared correctly

  
  from deephaven_server import Server
  s = Server(jvm_args=["-Dauthentication.psk=iris"])
  s.start()

from deephaven_ipywidgets import DeephavenWidget import deephaven.plot.express as dx from deephaven import time_table

tt = time_table("PT1S").update(formulas=[ "Latitude = Math.random()180.0 - 90.0", "Longitude = Math.random()360.0 - 180.0", "Magnitude = Math.random()*3 + 5" ])

fig = dx.density_mapbox(tt, lat='Latitude', lon='Longitude', z='Magnitude', radius=10, center=dict(lat=0, lon=180), zoom=0, mapbox_style="carto-darkmatter") display(DeephavenWidget(fig))

- Add support for opening DHC pydeephaven tables
  - Check if we're in a DndSession/the session_manager is there before trying to pull properties from it
  - Fixes #26, Fixes #27
  - Tested using the following snippet:
```python
from pydeephaven import Session
from deephaven_ipywidgets import DeephavenWidget
session = Session(auth_token="iris", auth_type="io.deephaven.authentication.psk.PskAuthenticationHandler")
tt = session.time_table(period=1_000_000_000).update("X=i")
display(DeephavenWidget(tt))

• Fetch figure/objects by name when using pydeephaven
  • Allow passing in an object by name and a session when using pydeephaven
  • Fixes #28
  • Tested using the following snippet:

    from pydeephaven import Session
    from deephaven_ipywidgets import DeephavenWidget
    session = Session(auth_token="iris", auth_type="io.deephaven.authentication.psk.PskAuthenticationHandler")
    session.run_script("""
    from deephaven import empty_table
    from deephaven.plot.figure import Figure
    t = empty_table(100).update(["X=i", "Y=i*i"])
    f = Figure().plot_xy(series_name="X vs Y", t=t, x="X", y="Y").show()
    """)
    display(DeephavenWidget("f", session=session))

• fix: Incompatibility with older versions of Jupyter
  • Fixes #30
  • Test by installing older version of notebook:

    pip install deephaven-server notebook==6.5.6 jupyterlab
    pip install -e ".[test, examples]"
    jupyter notebook

  • Then running in the Jupyter notebook:

    
    from deephaven_server import Server
    s = Server(jvm_args=["-Dauthentication.psk=iris"])
    s.start()

from deephaven import empty_table from deephaven_ipywidgets import DeephavenWidget t = empty_table(1000).update("x=i") display(DeephavenWidget(t))

With the incompatibility fix, does this mean the iframe will stay open when the kernel is restarted? If yes, is that something we should fix? Or at least create a ticket for? I'm not sure if there's a large amount of people using those older versions, and we could end up with dangling sessions (as was fixed for newer versions in #22)

[mofojed]

Yes, good call, we I'll create a ticket for older versions to handle. Lower priority though - it'll currently warn in the logs, and the session will eventually be cleaned up after hitting the ping timeout. https://github.com/deephaven/deephaven-ipywidgets/issues/31
