How to show continuous distributions (e.g., histogram, density plot)?

[bruceyyu]

This is a common issue for GWalkR.
In ggplot, users will often create a histogram to show the distribution of a continuous variable with geom_histogram in one step.

However, GWalkR takes a slightly different approach that requires more manual interaction, specifically with binning.
It requires users to first create bins manually before dragging the newly binned variable, along with its row count, into the appropriate fields, so users are more in control and aware of the decisions behind the visualization.
