A time-series line graph would be the best choice as it effectively shows the trend of Canadian GDP over time. It allows for easy visualization of changes and fluctuations in the GDP over the 70-year period. A cross-sectional bar-chart graph would not be as effective as it compares data for different years rather than showing changes over time. A scatter diagram would not be ideal as there is only one variable being analyzed. A logarithmic scale diagram would not be necessary as the data is not exponentially growing. Finally, a time-series pie chart would not be effective as it is difficult to compare the size of slices from year to year.
