Introduction

In this project we will draw a Bar Graph using a simple graphics library called Turtle GraphicsLinks to an external site.. The requirements are as follows:

Read data points from the given text file data.txt

Each data value is separated by a new line

Convert each data value into an int

print the list of data to the console window

sort the list of data

print the sorted list to the console window

Draw a bar graph of the sorted data

Algorithm

Use readlinesLinks to an external site. to read the data from the given file into a list

To sort the list, you can research a sorting algorithm of your choice or use the library sortLinks to an external site. function

Determine the maximum data value from your list as maxheight

Count the number of data values read as numBars

Scale your graphics window coordinates to fit a height of maxheight and a width of $40*$ numBars pixels

Use setworldcoordinatesLinks to an external site.

Add a little bit extra to the top right corner to create a border around your graph

To draw a bar graph of the given data:

Set your draw speed to fastest

Draw each data value as a rectangle with its height in pixels and a width $40$ pixels

Fill in each rectangle with color

Label the height of each rectangle, either above or below

Use the following functions:

begin$\_$fill$()$

end$\_$fill$()$

left$()$

forward$()$

right$()$

write$()$

Starter Code and Data File

Output

Your program should produce something similar to the following graphs. It is fine if they display one after the other:

Unsorted Bar Graph

Sorted Bar Graph
