This example shows the distribution of ratings across five categories—AI Research, Machine Learning Development, and others—using a stacked horizontal bar chart. Each bar segment represents the percentage of ratings within a rating band, such as "below 5.0" or "7.5-8.5". The visualization uses d3.stack() to structure the data and d3.scaleOrdinal for color mapping. Mouse interactions trigger tooltips that display exact percentages, while d3.axisBottom and d3.axisLeft label the chart. Data is loaded from a CSV file with d3.v7.
