This scatter plot displays the relationship between billionaires’ net worth (in thousands) and their age, with each circle representing an individual and hovering to reveal the person’s name via a SVG title tooltip. The visualization uses D3 v7’s reusable chart pattern, configuring linear scales for both axes and rendering axes with formatted tick labels. Data is fetched asynchronously from a CSV file hosted on GitHub Gist, while the chart’s width, height, and accessor functions remain customizable through getter-setter methods.
