Hi there! I have everything done except I cannot seem to do the bar graph. I am having trouble implementing it into my code, this is what I have so far any help would be greatly appreciated!

Write a GUI application with three labeled text fields, one each for the initial amount of a savings account greater than 0, the annual interest rate greater than 0, and the number of years greater than 0. Add a button "Calculate" and a read-only text area to display the balance of the savings account after the end of each year. Include another area with a bar chart that shows the balance after the end of each year All data entered by the user should be validated and there should be a quit or cancel button to end the program. Pressing the calculate button again will recalculate everything again. It is the programmer's responsibility to ensure that no matter what the user enters, the program does not crash. Call the program SavingsCalculatorViewer.java
