Which API allows drawing graphics on a bitmap via JavaScript?

• A. Geolocation API
• B. Drag and Drop API
• C. LocalStorage
• D. Canvas API

Answer: (D)

Drawing graphics on a bitmap with JavaScript is done with the Canvas API. The canvas element gives you a bitmap-based surface, and you obtain a 2D rendering context to issue drawing commands—things like rectangles, paths, text, and images. You can render directly to that bitmap and then display it on the page, or render offscreen first and then copy it onto the visible canvas. This makes it ideal for creating graphics, animations, games, or image editing workflows in the browser. The other options serve different tasks: location data, drag-and-drop interactions, and storing data locally—none of them provide the drawing capabilities that the Canvas API offers.
