Let's leave this to VegaFusion if this a concern for anyone.

Fixed by https://github.com/altair-viz/altair/pull/2735

Thanks for this PR @armsp. I like the visz on your project website: https://armsp.github.io/covidviz/, but I do feel that this PR is a bit complex, contains similar information to the...

There are a few variants possible. I'm not sure which one is wished here. The SO example using altair syntax: ```python import altair as alt from vega_datasets import data cars...

@hyerming23, maybe this is something that can help: ```python import altair as alt from vega_datasets import data cars = data.cars() brush_empty = alt.selection_interval(clear="pointerup") filter_on_up = alt.selection_interval(on="[pointerdown, type_anything] > pointerup", mark={"fillOpacity":0...

This spec is another example: [Open the Chart in the Vega Editor](https://vega.github.io/editor/#/url/vega-lite/N4IgJghgLhIFygG4QDYFcCmBneBtUscAjADQgBG8pIAxlWWFQL4kHwBMZlcnt94HFmzgBmLvzo8G8EUJCEALOKl8VjOAqYBdFiABmEGhijxQegJYYU6vmSgBPAA4Z4IAHYB7ALbm3qELqOEABOEF44cPjuYS5wIFhWGDRQGIxkCShJJgggDs6ujh6+JmQWVmARuAI6XL42mQDmGG5pIIiWAO6VbZ0A+kQgOlrpzpKgfl6xPRgd-SBkXiEA1qa5TlMovi5khcXwUMGYus00HmC+DaunKB7Bq2XWrq15U54+figBZAAe95aPcVgdnWrgAjmgIG4oOYYNDEC5dPY-uVXJRgfk4uDIdDYeZ4V8QB4gjQYUicqcWjDzB43KtkOhYtQgqEvK4MllUgT6Zh4AAGAB07AArExRWQACRYGgACwwi1c0qgUEcWDgAHo1fCGhB+Q0YdK0OR+dS1VLZYtNRhtQBaTYpTVCwX8gUAKywNICQA): ```json { "data": { "values": [ {"a": 1, "b": 1, "c": 1, "d": 1}, {"a": 2, "b": 2,...

That might be another issue. I think the problem here is that the `"point": true` will duplicate the spec under the hood somewhere into a layered version of a `line`...

Will changing this sentence (on line 170): ```typescript ...pointOverlay ``` into ```typescript ...omit(pointOverlay, ['name']) ``` be sufficient? It seems that `omit` is a custom function defined in `utils` which delete...

Nope, that is one level too deep. I think my suggestion will turn this: ```json "name": "foo" "mark": {"type":"point", "filled": true, "name": "bah"}, ``` into: ```json "name": "foo" "mark": {"type":"point",...

There is a contributing page in the repo. It mentions VS Code as preferable IDE: https://github.com/vega/vega-lite/blob/next/CONTRIBUTING.md#suggested-programming-environment. But I've no much experience in this either.
