This bubble chart visualizes smartphone specifications by mapping screen size to the x-axis, camera resolution to the y-axis, and price to bubble radius, with color encoding brand identity. The visualization uses d3.csv to load the smartphone dataset, then employs d3.scaleLinear for axes and sizing, d3.scaleOrdinal with d3.schemeSet3 for categorical colors, and d3.axisBottom and d3.axisLeft to render axes. SVG circles are appended and positioned using the scaled values, with opacity and stroke applied for readability.
