Higher-Level API

[maljovec]

Currently, the API for generating a plot is rather cumbersome. It was suggested that I should look into creating an interface that resembles matplotlib. This will cause a fair amount of work to design properly. My suggestion is to look into seaborn as an example since it can readily take in a pandas dataframe or operate directly on data. Given the highly structured nature of the data occurring in these plots, it would be useful to support something like how seaborn uses dataframes.
