This interactive bubble chart displays the relationship between screen size and price for a synthetic dataset of electronics, with each circle’s area encoding horizontal resolution. Rendered as SVG using D3 v7, the visualization employs `d3.scaleLinear` for the x, y, and radius scales, `d3.axisBottom` and `d3.axisLeft` for axes, and mouse event handlers (`mouseover`, `mousemove`, `mouseleave`) to show a tooltip with detailed specifications. The code reads data from `bubblechart.csv` and animates transitions on the tooltip’s opacity.
