A scatterplot displays eleven data points as circles, with a square root scale determining circle area based on the y-value. The visualization uses D3 v4.5.0 with `d3.scaleLinear` for x and y positioning and `d3.scaleSqrt` for radius mapping. Each circle includes a red text label showing its original coordinates. The SVG-rendered chart demonstrates how this scale creates proportionally smaller circles for lower values.
