This example visualizes the distribution of movie ratings across different genres, showing the proportion of films falling into five rating buckets from “below 5.0” to “above 8.5.” It uses a stacked bar chart approach, with each genre represented as a horizontal bar segmented by rating category. The code loads D3 via UNPKG and imports selection utilities like `select` from D3, while also demonstrating local ES6 module imports through a separate message file. The data comes from a local CSV file, and the rendering uses standard D3 SVG elements to display the proportional breakdown.
