altair and vega-lite version

[wangjiawen2013]

Hi,
Is altair version involved in vega-lite version ?
such as altair4 corresponds to vega-lite 4, while altair 5 uses vega-lite5 internally ?

More or less yes. Until now, each major VL release also required a major Altair release. Not sure if that is the case for the recent VL 6 release.
