A scatterplot displays individual medical insurance records from a CSV dataset, plotting each person's age on the x-axis against their insurance charges on the y-axis. All points render as steelblue circles with a fixed radius of 5 pixels. The visualization uses React with d3.v7, leveraging `scaleLinear` and `extent` to compute the axes, and a `data` join to bind the CSV rows to `circle` elements in the SVG.
