A bar chart visualizes the distribution of genres among the IMDb Top 250 movies, with each bar's height representing the count of movies in that genre and a tooltip showing the exact count and percentage. The visualization uses the D3.js library, including `scaleBand` and `scaleLinear` for axes and `axisBottom` and `axisLeft` for tick marks. Data is loaded from a CSV file, and genres are split and counted from a comma-separated field. The chart uses a Seaborn-derived color palette with interactive hover effects that highlight the selected bar and dim others.
