The holy grail distribution is a type of graph that is used to show how large or small the differences between different items. It is made up of two lines. The top line shows the highest number of something and the bottom line shows the smallest number of something. The lines show how close or far away the items are from one another. For example, if you have 10 apples and 10 oranges, the holy grail distribution will show the difference between the two items with the top line representing the 10 apples and the bottom line representing the 10 oranges. The lines will show how far away the two items are from each other.
