A scatterplot displays 11 data points as circles, with each point labeled by its x,y coordinates in red text. The visualization implements two linear scales for the x- and y-axes using `d3.scaleLinear()`, plus a square-root scale (`d3.scaleSqrt()`) to encode the y-values as circle radii. Vertical and horizontal axes are added using `d3.axisBottom()` and `d3.axisLeft()`, both with five ticks, and rendered as SVG groups. The chart uses a 500×300 SVG canvas with explicit padding.
