Feature request: Log-log and Semi-log plots

[russellcameronthomas]

It would be very helpful if viz.density and even viz.auto had options for log-log and semi-log plots, maybe similar to how ggplot2 does it in R:

• log = "x" and log="y" for semi-log, and log = "xy" for log-log

This feature is very important for comparing or evaluating heavy tailed distributions and the likelihood of very-large-but-rare events. Right now my only option is to export the data to R or similar.
