Python tool for generating visualizations fast

I saw about a month ago or so someone posted their tool they made in Python. It looked like you could just write a few lines to point to a data source, write a query against it with a method and then generate a webpage with a visualization automatically generated. The use case made it seem like you could very quickly take data and explore it this way without needing to get really fancy with dashboarding tools or ML algorithms and such. Anyone know what I'm talking about? I don't think it was pyspark because it seemed like a small open source project that one person worked on
