Final answer:
A line graph, specifically a time series graph, is the usual term for a visual graphic chart for plotting scheduling and progress.
Step-by-step explanation:
A line graph is often the most effective format for illustrating a relationship between two variables that are both changing. For example, time series graphs can show patterns as time changes, like the unemployment rate over time.
One common line graph is called a time series, in which the horizontal axis shows time and the vertical axis displays another variable.
Thus, a time series graph shows how a variable changes over time. Figure A5 shows the unemployment rate in the United States since 1975, where unemployment is defined as the percentage of adults who want jobs and are looking for a job, but cannot find one. The points for the unemployment rate in each year are plotted.
