Visualization of dataframes

[aryx]

I could not find any documentation in the tutorial book about how to visualize dataframes.
Is there any function I could use?
My main use is to store benchmak information in a dataframe where different variants of a compiler applied to different repositories and for each variant/repo I have a time information in second. I'd like to visualize which variant is the fastet by plotting a box for each variant and multiple graphs next to each other for the different repositories.
