This scatterplot visualizes the relationship between the age and wealth of billionaires, sourced from a CSV file. Each purple circle represents a billionaire, with its position determined by age on the x-axis and wealth in billions on the y-axis. The visualization uses D3.js version 7 within an SVG rendering to create the plot, axes, and labels. The code employs `d3.csv` to load the data, `d3.scaleLinear` for scaling, and `d3.axisBottom` and `d3.axisLeft` to construct the chart axes.
