That would be great! We have tried to document how to contribute at this page, https://github.com/altair-viz/altair/blob/master/CONTRIBUTING.md. If you face any difficulties, just send me a message and I will try...

(another recent PR including a new example that you can use as reference is the following: https://github.com/altair-viz/altair/pull/2882)

Really nice notebook @thomascamminady! Love it. Two suggestions for the visualization (very well done btw!): 1. If you add `domainMid=0` as attribute to the scale for the color of the...

I think it's good to discuss this, but indeed to a wider scope. I had the same with aggregates, instead of `alt.X("mean(foo)")` to introduce something such as `alt.X(field="foo").mean()`, or `alt.X().agg("mean")`

Not exactly sure since there are likely more options that could be explored using the `binding` function, see: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input

Really nice. Yes. An example for this would be great. Maybe a new section named 'binding' and then an example per bind type?

Instead of a condition for opacity highlighting you should include a filter transform. ```python import altair as alt from vega_datasets import data search_box = alt.param( value='', bind=alt.binding( input='search', placeholder="Car model",...

You would need to make use of an interactive JupyterChart object ([docs](https://altair-viz.github.io/user_guide/jupyter_chart.html)). As such: ```python import altair as alt from vega_datasets import data import ipywidgets # define a text and...

The intention of this PR is not exactly clear, but is the following issue + comment related here? https://github.com/vega/vega-lite/issues/8230#issuecomment-1179213186 Also, when is this code invoked? I think this param lifting...

Maybe it is possible to register these composite projections, like http://geoexamples.com/d3-composite-projections/ into Vega, see https://vega.github.io/vega/docs/projections/#register how to do this.
