This dot plot visualizes the ages of billionaires, with each green dot representing one individual’s age along the y-axis and their sequential index on the x-axis. The p5.js sketch loads a CSV dataset in `preload()` using `loadTable`, filters out zero-age entries, then renders axes, tick marks, and axis labels in `draw()`. It uses `map()` to scale data points, `ellipse()` for the dots, and `line()` for the chart framework, all within a 900x600 canvas.
