This interactive bubble chart, built with D3.js v7 and SVG animation, visualizes the correlation between processor speed (x-axis), battery capacity (y-axis), and camera resolution (bubble size) across 32 smartphone brands from a CSV file. Each bubble is color-coded by brand using `d3.scaleOrdinal` and `d3.interpolateTurbo`, with a tooltip revealing brand names on hover via mouse events. The chart includes labeled axes, a circle-based legend for camera megapixels, and uses `d3.axisBottom` and `d3.axisLeft` for scales. The semi-transparent bubbles enhance visibility, while hover effects increase opacity.
