This interactive bubble chart visualizes the relationship between smartphone price, battery capacity, and average rating using data from a CSV file. The visualization uses D3 v7 to render SVG circles positioned by price and battery on x and y axes, with bubble size representing rating and color distinguishing phone models via an ordinal scale with interpolateTurbo. Hover interactions trigger tooltips displaying model details. A legend on the right maps bubble sizes to star ratings, while CSS styles enhance hover opacity for improved readability.
