with resolving of vega/vega-lite#4939 I guess it could be simplified. |

Should we wait for that update, or merge as-is? |

I prefer using the form alt.datum.Miles_per_Gallon > 0

I prefer binned=(alt.datum.bin_max + alt.datum.bin_min) / 2
Seems like density plots are quite requested (#1494, #1029) and with new impute transform we can somehow visualize density. I don't how (and when) vega/vega-lite#4939 will be resolved it may be that vega/vega-lite#3442 will be resolved first. I opend #1529 as reminder (if you assign it to me, I'll fix it) |
