+/// This function generates `(x, y)` data based on a function to use in other equations.
+/// - equation (function): A function that accepts the `x` value of the data and returns the proper `y` value.
+/// - start (integer, float): The first `x` value that should be generated.
+/// - end (integer, float): The last `x` value that should be generated.
+/// - precision (integer): How many lines should be plotted between the `start` and `end` value. The higher the value, the more precise the data will get.
