Everyone I know at $big_research_lab uses it and hates it. But what are the alternatives really? Altair plots are larger than you dataset, plotnine has totally unusable docs and insane behaviour in some places (look up what plotnine's gg.ylims does; I'd bet it's caused more than one peer-reviewed error.), and further seems to have basic operations like drawing a vline scale in slowness with the size of your data. Plotly is commercial, raw d3 is inconvenient from python. The situation is deeply unfortunate.
