I would say hands down, plotnine. It... * is a port of ggplot2 to python * has a very active maintainer I've been testing out porting a bunch of analyses from R to python, and it has been very easy to swap in for ggplot2. The biggest downside I can see is that with ggplot2 it's easy to convert to interactive using plotly (but there isn't that kind of support for plotnine yet). https://github.com/has2k1/plotnine https://github.com/has2k1/plotnine
