This interactive scatter plot visualizes the relationship between release year and rating for the IMDB Top 250 movies, with each dot colored by primary genre. A toggle button switches between the standard scatter view and genre-specific average trend lines computed per decade. Built with React and D3 v7, it uses `scaleLinear`, `scaleOrdinal`, and `schemeCategory10` for axes and color encoding, while the trend lines aggregate ratings by genre and decade. The chart updates dynamically through React state, recomputing scales and rendering with D3 selections.
