This bubble chart visualizes the relationship between price, battery life, and weight for various smart device brands. Each circle's horizontal position represents price, vertical position represents battery life, and radius encodes weight. Color distinguishes brands, with a legend for weight values and brand names. The chart uses D3.js v7 with `d3.scaleLinear` for axes and bubble sizing, `d3.interpolateTurbo` for color mapping, and loads data from a local CSV file.
