This bar chart visualizes the distribution of genres among IMDb’s Top 250 movies, showing how many films fall into each genre category. Using D3.js v7 within a React component, the code loads movie data from a CSV file, splits each movie’s comma-separated genre list, and counts occurrences to create the dataset. The chart employs scaleBand and scaleLinear for positioning, with bars colored via a linear color gradient from light to dark blue. The y-axis represents genre counts, while rotated labels on the x-axis identify each genre.
