A grid of points
In the video, you saw how it can be instructive to use a contour plot over a grid of points to see what the anomaly score might have been at locations other than where the data occurred.
In this exercise you'll create and visualize a grid of points across the region of interest. The grid you create will be used in the exercise that follows to visualize predicted isolation scores.
