This horizontal bar chart visualizes the sum of Google Play Store app reviews across categories, with each bar colored by content rating. The bars are sorted by total reviews, making top categories like games and communication easy to identify at a glance. Built using the vega-lite-api library, it loads data via d3's CSV parser and renders an interactive SVG with tooltips displaying aggregate review counts. The visualization applies a custom config for cleaner axes and labels, and uses automatic sizing to fit the browser window.
