This bubble chart displays 20 randomly generated data points, each positioned by x and y coordinates with a size value controlling the bubble radius. The visualization uses D3.js version 7 to render an SVG, employing d3.scaleLinear for the x-axis, y-axis, and bubble size scales, along with d3.axisBottom and d3.axisLeft for the chart axes. The dots appear as semi-transparent circles (fill-opacity 0.5), plotted directly from JavaScript-generated random values without any external data file.
