I'd like to +1 / bump this issue. I was surprised to be unable to add a title to categorical legends!

Hmm. Not sure offhand what is driving the issue, as it appears at first glance to stem from Apache Arrow. In the meantime, you might consider filing an issue with...

This is incredibly valuable feedback. Thank you @frankelavsky.

Currently tooltip handling is performed via JS logic. However, it is possible we could augment the `SVGStringRenderer` to include `title`-based tooltips for static output. Flagging as a feature request.

I love column stores but they are not a panacea, particularly in a non-compressed, memory-resident setting like Vega. A few thoughts: First, there is the potential data copying cost: for...

The (safe) use of a `Function` constructor underlies multiple Vega features, including not only expressions, but also compilation of visual encoding procedures. It's unlikely that we (at UW) will focus...

Hi @einsweniger, if you know ahead of time all the Vega specs you want to use in production, then yes, you could run parse ahead of time. The output of...

Here is one related proposal, let me know if it would suffice: the output of Vega parser could be passed to a post-processor that performs code generation for all generated...

Here is a quick overview of the situation. Vega uses the Function constructor in multiple places: 1. In vega-util utilities (`field`, `key`, and `compare`) 2. In vega-transforms to generate aggregation...

You can follow #2598 to see upcoming changes relevant to this issue. The PR removes Function constructor use in utilities and redesigns the encoders to run through the expression parser,...
