This interactive quiz asks multiple-choice questions about humpback whales, tracking the user’s score and displaying a final results screen with a percentage and restart option. Built with Svelte, it uses component state and derived values to manage the current question, answer selection, and progress, with DOM events for user interaction. The data comes from an embedded quizData.js object, and the UI relies purely on Svelte’s reactive declarations and CSS styling—no external visualization libraries are involved.
