A scatterplot displays ten data points on a 500-by-100 SVG canvas, with each circle positioned according to its x and y coordinates. The circle radius is computed as the square root of the difference between the canvas height and the y-value, creating larger points toward the bottom. Built with D3.js version 4.5.0, the visualization uses the `selectAll`, `data`, and `enter` pattern to bind the dataset and append circles, setting the `cx`, `cy`, and `r` attributes through anonymous functions.
