Quizplus · Accepted Answer

A time-series line graph is the best way to illustrate the trend of Canadian GDP over time, as it shows the changes in GDP over a continuous period. A cross-sectional bar-chart graph and a time-series pie chart are less appropriate as they do not show changes over time. A logarithmic scale diagram and a scatter diagram are also less appropriate as they do not show the trend of GDP over time.
