Final answer:
A time series graph, which is a type of line graph, effectively shows how variables change over time, such as unemployment rates.
Step-by-step explanation:
Time series graphs can be used to visualize trends in counts or numerical values over time. Because date and time information is continuous categorical data (expressed as a range of values), points are plotted along the x-axis and connected by a continuous line. Missing data is displayed with a dashed line. A line graph is the simplest way to represent time series data. It helps the viewer get a quick sense of how something has changed over time.
A detailed allocation of work effort displayed by time period can be illustrated in a graphical format known as a time series graph. This line graph is particularly effective at showcasing how a variable changes over time. For instance, it can elucidate trends such as the unemployment rate over a span of years. The horizontal axis typically denotes time, while the vertical axis represents the variable in focus. The data points for each time period are plotted, with lines connecting them to illustrate the progression or pattern over time.
