Customizing the actions links in the Altair charts

[sgsfak]

Describe the bug

It seems that disabling the actions links in the Altair charts using altair.renderers.set_embed_options(actions=False) does not work. I am not sure whether it's marimo's or altair's issue. It's probably the latter since the same problem has been reported for streamlit.

The workaround proposed in the Streamlit's discussion here is to do the following per chart:

chart["usermeta"] = {
    "embedOptions": {
        "actions": False,
    }
}

Environment

{
  "marimo": "0.8.13",
  "OS": "Darwin",
  "OS Version": "23.6.0",
  "Processor": "i386",
  "Python Version": "3.12.2",
  "Binaries": {
    "Browser": "128.0.6613.121",
    "Node": "v18.17.0"
  },
  "Dependencies": {
    "click": "8.1.7",
    "importlib-resources": "missing",
    "jedi": "0.19.1",
    "markdown": "3.7",
    "pygments": "2.18.0",
    "pymdown-extensions": "10.9",
    "ruff": "0.6.4",
    "starlette": "0.38.5",
    "tomlkit": "0.13.2",
    "typing-extensions": "4.12.2",
    "uvicorn": "0.30.6",
    "websockets": "12.0"
  },
  "Optional Dependencies": {
    "altair": "5.4.1",
    "duckdb": "1.0.0",
    "pandas": "2.2.2",
    "pyarrow": "17.0.0"
  }
}

Code to reproduce

import marimo as mo
import pandas as pd
import altair as alt

alt.renderers.set_embed_options(actions=False)

df = pd.DataFrame({"x": [1,2,3], "y": [10,20,30]})

chart = alt.Chart(df).mark_point().encode(x="x", y="y")
mo.ui.altair_chart(chart)

## However, using the following per chart works:

chart["usermeta"] = {
   "embedOptions": {
       "actions": False,
    }
}

mo.ui.altair_chart(chart)

Thanks for the detailed issue. I am surprised that altair does not handle this internally, but using your workaround, I can make this embedOptions set globally are always set on all charts.
