This example shows a scatter plot of coordinate pairs plotted with D3.js version 4.5.0. It renders circles and red text labels in an SVG canvas, using `d3.scaleLinear` for x and y axes and `d3.scaleSqrt` for circle radius sizing based on the y-value. The X-axis is customized with `d3.axisBottom` and `tickValues` to display only four specific tick marks (0, 100, 250, 600), demonstrating how to reduce axis clutter.
