This scatter plot visualizes the IMDB Top 250 movies dataset, mapping each film's release year on the x-axis against its user rating on the y-axis. Each point represents a movie, colored by its primary genre, revealing trends in how ratings have evolved over cinema history. Built with React and D3.v7, the implementation uses `scaleLinear` for axes and `scaleOrdinal` with `schemeCategory10` for genre coloring. The code reads from a local CSV file, applying numeric coercion before rendering the visualization with the `viz` function.
