From the options listed, which is the most effective way to visually represent the monthly electricity expenses expected for Daniel over a year, allowing for easy comparison between months?

A bar graph is effective for comparing electricity expenses across separate categories—in this case, the months of the year. With months on the x-axis and expenses on the y-axis, the bar heights make it easy to see which months cost more or less. A table lists the values but is less visual, while a pie chart emphasizes parts of the annual total rather than month-to-month comparisons.
