Plot a function represented as `x', `y' numerical arrays.
Post link to your resulting image for input arrays (see Example section for Python language on Query Performance page):
x = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}; y = {2.7, 2.8, 31.4, 38.1, 58.0, 76.2, 100.5, 130.0, 149.3, 180.0};
This task is intended as a subtask for Measure relative performance of sorting algorithms implementations.
