Which is easier to sketch relatively accurately, a pie chart or a bar chart? A. A bar chart is easier because sketching the exact percentages is more challenging in a pie chart. B. A pie chart is easier because estimating the sizes of the slices in a pie chart is easier than estimating the heights of the bars in a bar graph. C. A pie chart is easier because a pie chart has one shape (a circle), which is easier to graph more accurately than a bar graph, which has multiple shapes (multiple rectangles). D. A bar chart is easier because the bars are always in decreasing order of category percentages, which makes comparisons of categories easier
