A bar chart is the ideal graphical representation for comparing a single variable across different groups as it clearly displays the differences between groups. Each group is represented by a separate bar, and the height of the bar represents the value of the variable. This allows for easy comparison between groups. The other options (histogram, scatter plot, time series graph) are not ideal for comparing a single variable across different groups as they either display the distribution of a variable (histogram), the relationship between two variables (scatter plot), or changes in a variable over time (time series graph).
