This stacked bar chart compares the distribution of game ratings across eight gaming platforms, with each colored segment representing the proportion of games falling into a specific rating range from below 5.0 to above 8.5. The visualization uses d3.stack to transform the raw percentage data, d3.scaleBand for the categorical platform axis, and d3.scaleLinear for the percentage scale. The chart is rendered as SVG elements with a custom ordinal color scale differentiating the five rating categories, making it easy to compare the rating profiles of platforms like Steam and PlayStation.
