This dot plot compares the average net worth of billionaires across different inheritance categories, from non-inherited wealth to those inherited through a spouse or widow. The p5.js sketch loads a filtered CSV dataset from the Corgis billionaires collection via `loadTable`, then renders labeled axes with tick marks and grid lines. It places each category label along the x-axis while computing the plotted positions from the average worth values in billions, though the visual encoding relies on the canvas drawing API rather than a dedicated charting library.
