This scatterplot visualizes movie runtime against rating, with each fixed-radius circle representing a film and colored by simplified genre. The chart includes hover tooltips displaying movie name, primary director, and release year. Data loads from a CSV and is preprocessed using custom genre aggregation, runtime parsing, and numeric conversion logic. The visualization is built with React and D3 v7, using `scaleLinear`, `scaleOrdinal`, `schemeTableau10`, `axisBottom`, and `axisLeft` for axes, scales, and legends.
