This interactive bubble chart visualizes smartphone specifications, comparing screen size, camera resolution, and price across different brands. Each bubble’s position encodes screen size on the x-axis and camera resolution on the y-axis, while its radius represents price and its color indicates the brand. The visualization uses D3.js (v6) with an SVG rendering approach, employing `d3.scaleLinear` for the axes and bubble sizing, `d3.scaleOrdinal` with `d3.schemeSet3` for brand colors, and `d3.axisBottom`/`d3.axisLeft` for labeled axes. Data comes from the `smartphones.csv` file, loaded via `d3.csv`, with each point styled with opacity and a black stroke.
