2. (20 pts) Write a Python script to load and plot the data in file "river stage-Chicaggo.River.txt". This file contains the river stage records in meters at two gauge stations on the Chicago River. Make a plot to show the relationship between the stages at the two stations. Show the data with scatter plot. Make sure you have all the basic elements of a "good" plot, e.g., axis title including units, ticks, marks, proper font size, etc. Note: the provided data file uses "tab" as separator for the two columns of data.

See the documentation of the data file reader Python functions for details. The following is one example plot
