Plot coordinate pairs

Plot coordinate pairs
You are encouraged to solve this task according to the task description, using any language you may know.

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.

Library: plot

   load 'plot'
   magnitudes =: 2.7 2.8 31.4 38.1 58.0 76.2 100.5 130.0 149.3 180.0
   'dot; pensize 2.4' plot magnitudes

Output of plot.
