Jake and company are doing nice work here. By comparison to the R community, I feel that the Python community sometimes swashbuckles toward new libraries without always doing a good review of prior art. Not so in this case. Vega / Vega-lite are doing something cool, namely bringing the grammar of graphics to the web. By extension, Altair may not be the only plotting library you need in Python, but it's rapidly becoming the one I'd look to first.
