Learn how to create standard line, bar, and pie plots.
- [Instructor] Standard chart graphics are excellent tools…for conveying simple data insights in a way…that anyone can understand.…For example, imagine you're an e-commerce business…analysis for a company that just makes…some major changes to its website layout.…You're putting on site usability…to convey findings to your manager,…you use a line chart, a bar chart, and a pie chart.…Use the line chart to show how the total…number of items purchased per day has…increased since the change.…
