A P5 bar chart visualizes natural gas prices in California over time, with bars representing prices for each year sampled from an external CSV dataset. The chart highlights that 2005 had the highest price, with an annotation noting a connection to the recession. Using p5.js, the code loads data via `loadTable`, renders rectangles with `rect()`, and displays axis labels and annotations through `text()`. A loop iterates through rows, scaling price values to bar heights, while grid lines are drawn using `line()`.
