Y, X The Y and X columns become the y and x coordinates of the bubbles in
the plot. These values can be continuous or categorical (nominal or
ordinal).

(Optional) ID variables identify rows that should be aggregated and
shown as a single bubble. The default coordinates of each bubble are the
averaged x and y values, and the default size of each bubble is the sum of
the sizes of all aggregated members. See “Specifying Two ID Variables”
on page 386.
Maintains separate coordinates, sizes, and colors for each unique time
period. The bubble plot shows these values for a single time period. For
example, if the Time column contains years, the bubble plot is updated
to show data by each year. See “Specifying a Time Variable” on page 386.
Controls the size of the bubbles. The area of the bubbles is proportional
to the Size value. There is a minimum bubble size, to keep bubbles
visible, even if the size value is zero. If Size is left blank, the default
bubble size is proportional to the number of rows in that combination
of Time and ID.
Colors the bubbles according to the selected variable. If the selected
variable is categorical (nominal or ordinal), each category is colored
distinctly. If the selected variable is continuous, a gradient of colors is
used.
Place a column here to produce a separate bubble plot for each level of
the variable.
