Final answer:
A line graph can be used to display a series of connected lines on a map, ideal for showing trends and relationships between two changing variables, such as time series data or geographical distribution patterns.
Step-by-step explanation:
You can use a line graph object to display a series of connected lines on a map. Line graphs are particularly useful for showing trends and changes over time, such as the geographic distribution of a specific allele or the path of a moving object. They effectively illustrate relationships between two variables that are both changing, making them the preferred method in various applications like tracking the unemployment rate or creating a detailed topographical map.
For instance, if we consider a map that showcases the frequency of a genetic trait across different populations, a cline line could be used to connect these populations on the map. Similarly, a dashed line on a simple map can depict a path that has been traveled, which exemplifies making a connection using a line graph. In summary, line graphs are dynamic tools that help in visualizing and interpreting data over time or distance on a map.
