This example visualizes the top 100 movies by IMDB rating as a horizontal bar chart, though it currently displays only the first five entries from a CSV dataset. The chart uses React for component state management, with D3 v5 handling scales, axes, and data loading via `d3.csv`. Marks are rendered as SVG `<rect>` elements, with `scaleBand` for the y-axis and `scaleLinear` for the x-axis, and the code draws custom tick labels and gridlines. It encodes movie names and ratings through spatial position and bar length.
