This interactive stacked bar chart visualizes IMDb movie rating distributions across six genres, with each bar segment representing the proportion of movies within specific rating brackets. The chart uses D3.js (v7) with an SVG rendering approach, employing `d3.csv` to load data and `d3.stack` to create the stacked segments. A legend maps five rating categories to a color scale, while mouseover events trigger tooltips showing exact percentages for each genre-rating combination. The code also demonstrates custom axis styling and font integration.
