Answer to Question 2
When interpreting and analyzing a graphic, avoid a mere restatement of what the graphic obviously shows. Instead, emphasize the main point you are making. Your analysis may include summary statements about the data, compare information in the figure to information obtained from other sources, or extend the shown data into reasonably supported speculative outcomes. Strive to transition naturally from the discussion of the graphic into the next point you wish to make.
