Vega-Altair: Declarative Visualization in Python

Found it while researching visualisation tools for python. The plots in the examples look really neat, but the 5000 row limit (https://altair-viz.github.io/user_guide/large_datasets.html) is rather restrictive for some of my use cases, e.g. big interactive time series.

Has anyone on HN used it and found useful? What are the benefits?
