1. Why is the color palette back and white for colored plots

2. I think our tick counts are way higher than ggplot normally does.

ad 2) ggplot distinguishes between minor and major gridlines. So tick count may be lower while the gridline count may be similar.

Agree with 1. I would keep the default colors.
Also I would consider changing background for bar charts. It can be achieved by adding view: {fill: '#e5e5e5'} to config.

I don't have time to make these changes but would be happy to review a pull request.

Is it normal that only categorical data has a custom palette ?
I can't reproduce the rendering of https://vega.github.io/vega-themes/?theme=ggplot2 using altair

[domoritz]

I don't understand your question. Continues scales can also have a custom scheme.

Altair just generated Vega-Lite so there could be an issue with the particular renderer you use that doesn't load the theme. This is likely not an issue with the repo here.
