This example shows the distribution of 2015 U.S. Math SAT score averages for students with an A-GPA across each state, using a horizontal boxplot to summarize the data. The visualization loads a CSV file from a GitHub gist and calculates quartiles and the median from the score column. It renders the box, whiskers, and axis ticks using p5.js drawing functions like `rect`, `line`, and `text`, with a quantile helper function for statistical summaries.
