It is a cross-section of the three-dimensional graph of the function f (x, y) parallel to the x, y plane. To convert to an actual probability, we need to find the area. The function bscols() (for bootstrap columns) is used to array two plotly objects; the first of these is a scatterplot, and the second is a choropleth map of population density. In other words, height and width must be specified at runtime to ensure sizing is correct. It shows the distribution of values in a data set across the range of two quantitative variables.
