Graphing with Tkinter

Tkinter is not a graphing tool. However, should you need to draw graphs with Tkinter, you can use the Canvas widget to draw graphs.

In this iteration, we will draw the following graphs:

• Pie chart (7.13_pie_chart.py)
• Bar graph ( 7.14_bar_graph.py)
• Scatter plot (7.15_scatter_plot.py)
