As a newly hired data scientist for a bookshop, the owner has tasked you to build a visualization tool to help the organization make better business decisions using data. Last week, KPI's (key performance indicators) were addressed and your goal was to develop a tool that can provide an answer for a particular audience. This week, you will get the data ready for visualization and students will have much more freedom and variation in what they prepare. Your task is to create a unique and distinct visualization for the bookshop. What type of visualization would you create?
1) Bar chart
2) Line graph
