Which of the following web technologies is primarily used to create interactive graphics?

The choice of Flash as the technology primarily used to create interactive graphics reflects an older approach to web development. While Flash was well-known for its ability to create rich animations and interactive content, it has since become obsolete due to various limitations, including performance issues, security vulnerabilities, and the fact that it requires a plugin that is no longer supported by most modern browsers.

Focusing on web technologies used today, JavaScript is the preferred choice for creating interactive graphics. It is a powerful scripting language that works seamlessly with web technologies like HTML and CSS to enhance user interactions. With JavaScript, developers can manipulate the Document Object Model (DOM), respond to user events, and interface with graphics libraries such as Canvas and WebGL, which are specifically designed for drawing and rendering interactive graphics.

While CSS is typically used for styling elements on a webpage and HTML defines the structure, neither of these technologies is primarily responsible for creating interactive graphics. JavaScript stands out as the cornerstone of web interactivity and is widely supported across all major browsers, making it the modern and effective option for creating dynamic graphics and user experiences.
