Coloring student scores bar graph

The school board was well-pleased with your previous plot, but they are wondering if there is a way for you to visually identify good and bad performers.

This would be a great opportunity to utilize color, specifically a color scale. You think a scale from red (worst marks) to green (good marks) would be great.

Part of your previous code to create the student scores bar chart has been provided.

The student_scores DataFrame is also available. You can print it out and inspect it in the console.
