This bubble chart displays the correlation between smartphone specifications and price for 15 brands. The x-axis represents screen size in inches, the y-axis shows RAM in gigabytes, while the bubble radius encodes price, and color distinguishes brands. Hovering over a bubble reveals a tooltip with detailed specifications. The visualization is built with D3 v7 and renders SVG and animations through custom JavaScript, using d3.scaleLinear for axes and bubble size, d3.scaleOrdinal for colors, and d3.interpolateTurbo for the color gradient.
