Visualizing evolution

As an aspiring data visualization expert, you've gotten to train a young analyst from the Finance department on charting techniques. Clearly, there is a lot he can learn from you already! Can you salvage his "Quarterly Sales evolution" chart and propose a better alternative?

If you lost progress, close any open reports and load 3_1_quarterly_sales_evolution.xlsx from the Workbooks folder.

You can complete this exercise on DataCamp in a browser-based Excel session or locally if you have Excel and Copilot.
