I wanted to bring up something Aryan mentioned in this ticket in on the subject of recent contributions by Ven and himself visualizing Git data https://github.com/sbenthall/bigbang/issues/136#issuecomment-75007815 There are now a few different Git-related notebooks in the repository. It would be good if we could standardize on: * coding patterns -- will we be creating new objects to represent Git data or will we depend on the preprocessed Pandas dataframe? I see advantages to either. * notebook idioms -- we should come up standards for what gets including in notebooks and what gets pushed to underlying libraries so the notebooks stay clean is possible. * visualization idiom -- the out-of-the-box networkx graph visualizations are a good start but not pretty. We have some options for graph visualization, including more artful use of what networkx/matplotlib gives us, use of d3 within notebooks, etc. It would be cool to have a coherent set of design principles for this.
