This bubble chart visualizes the correlation between processor speed, RAM, and battery life for various devices, with each circle's size encoding battery life and color representing the device category. Built with D3 v7, it renders as an SVG and includes interactive tooltips that display the exact specifications on hover. The chart uses `d3.scaleLinear` for x/y axes and bubble radius, while `d3.scaleOrdinal` maps device names to color categories. A legend shows both the battery-life scale and color-coding, drawn from the gadgetdata.csv file.
