14. Be able to describe a use case for each of the following: bar chart, thematic map, line graph, and physical map.
1) Bar Chart: A bar chart can be used to represent and compare quantitative data across different categories or groups. For example, it could be used to show the sales performance of different products in a company, with each bar representing the sales figure for a specific product.
2) Thematic Map: A thematic map is used to visualize spatial data and highlight patterns or relationships between different geographic areas. One use case could be visualizing population density across different regions, with darker colors indicating higher population concentration and lighter colors showing sparser areas.
3) Line Graph: A line graph is commonly used to display trends or changes in data over time. It can be used to depict the stock market performance of a particular company, with each point on the line representing the stock price at a specific time, thereby showing the fluctuation in value over a given period.
4) Physical Map: A physical map provides a visual representation of the physical features of an area, such as mountains, rivers, and plains. It can be useful for displaying geographical information, such as the elevation or topography of a region, in a visually informative way.
