The following data has been collected: [table]
Year | Total Sales 2016 | 25623 2017 | 27880 2018 | 30210
[/table] Which graph type would be the most suitable to show the Total Sales over time?

To determine the best graph for showing Total Sales over time, we first restate the scenario and options to ensure clarity.
Option a: Pie graph. Pie charts are designed to display proportions of a whole at a single point in time, comparing parts to a total. They are not ideal for illustrating changes across multiple time periods, since they don’t convey trends or trajectories over time.
Option b: Line chart. Line charts are specifically suited for time-series data because they plot data points in chronological order and connect them with a line, making it easy to observe increases, decreases, and overall trends across years.
In this dataset, you have Total Sales for 2016, 2017, and 2018. Visualizing these three (or more) sequential points as a line graph allows a viewer to quickly perceive how sales evolve year by year, including whether sales are rising or falling and at what rate. The line provides continuity between the points, which is useful for detecting smooth trends or abrupt changes.
Alternatively, if the goal were to compare parts of a whole within a single year, a pie chart might be appropriate, but not for showing a progression over time. Pie charts become cluttered and less informative when used to display multiple time points, and they fail to convey temporal relationships.
Therefore, Option a is not suitable for the goal of showing Total Sales over time, whereas Option b directly aligns with the objective by illustrating the temporal trend through connected data points.
