Abstract: The bridge plot is used to visualize the famous Iris data. With the help of trellis system to condition the data on species, the plot presents four iris flower traits in their original units within a single panel. Such a plot can be employed when among four variables there are two groups each consisting of two variables having the same and comparable units.
Keywords: Original units, parallel coordinate plot, scatterplot matrix
