This visualization plots the number of “thumbs up” each user review received against its row index in a dataset of Google Play reviews for the Oppenheimer mobile app. It renders the data as green circular points rather than traditional bars, using D3 scales and axes, with hover interactions that enlarge points and clicks that select and dim unselected points. The React component manages state and dimensions, while D3’s CSV loader, linear scales, and axis generators handle data parsing and chart rendering.
