Sometimes you may want to include more complex patterns of interactivity into a plot, for example where interaction with one plot elements triggers changes or appearance / disappearance in a wider group of other plot elements.

The example below builds up a plot with more complex interactivity based on these principles.
# Set data
x_vals <- iris$Sepal.Length
y_vals <- iris$Sepal.Width
z_vals <- iris$Petal.Length
point_cols <- rainbow(
