This example displays a basic scatter plot of ten data points, each represented by a circle and a red text label showing its coordinates. The visualization uses D3.js v7 to append SVG circles and text elements to the document body. Circle radii are calculated as the square root of the difference between the plot height and the y-coordinate, creating a size variation tied to vertical position. The chart is drawn with a 500 by 100 pixel viewport, using the data array directly as the source for positioning.
