This bubble chart visualizes the correlation between processor speed, RAM, and display size for various smartphone makes. Each circle's x-position maps to processor speed, y-position to RAM, and radius to display size, while color encodes the phone manufacturer. The chart uses D3.js v7 with SVG rendering, incorporating scales for positioning, color, and size, alongside interactive tooltips that display phone make on mouseover. Data comes from the included `phones.csv` file, with axes labeled and a legend explaining the bubble sizing.
