Final answer:
Visualizations like pie charts and bar graphs are used to glean insights from data. Pie charts represent percentage of categories within a whole, while bar graphs are good for category comparison. It is crucial to choose the right type of graph and consider presentation elements for accurate data interpretation.
Step-by-step explanation:
A visual visualization is used to gain insights while interacting with the data.
Tables are a good way of organizing and displaying data, but graphs such as pie charts and bar graphs provide a deeper insight into understanding data. Pie charts are especially useful when we want to show parts of a whole as each wedge in the circle represents the percentage of individuals or items in each category.
When it comes to choosing which graph to use, consider the data and the message you want to convey. A pie chart is most appropriate when displaying relative proportions or percentages of a whole, while a bar graph is better suited for comparing quantities across different categories. It is important to make mindful decisions about the data included, how it's divided up, and the scales used, as these choices can greatly affect the interpretation of the data presented in the graph.
