This bar chart visualizes the total revenue collected from first, second, and third class passengers on the Titanic, revealing that second class generated the least income. The chart is rendered using p5.js, with data loaded from a CSV file via `loadTable`. The `setup()` function creates a full-window canvas, and `draw()` computes cumulative fares per class from the `Pclass` and `Fare` columns, then draws horizontal bars scaled to revenue values along labeled axes. Axis tick marks increment by thousands to indicate revenue amounts.
