Explanation:

Adding charts and graphs is usually in an "Insert" tab. Adding transitions or animations is often in an "Animations" tab. The "Design" tab is where you can change slide themes (pre - designed color, font, and graphic element sets) and layouts (how placeholders for text, images, etc. are arranged on a slide).
