This example visualizes the distribution of mushroom stem lengths using a box plot. It displays the minimum, maximum, median, and interquartile range of the dataset, which is loaded from a CSV file. The visualization is built with the p5.js library, using its `createCanvas`, `loadTable`, `sort`, and drawing functions. Data is processed by computing quartiles and the median, then rendered as a vertical line for range, a rectangle for the interquartile range, and a line for the median on a 500×500 canvas with custom axis labels.
