This area chart displays car model names along the x-axis against the number of doors on the y-axis, using a single line with a semi-transparent fill. The visualization is rendered on an HTML canvas using the Chart.js library, which fetches its data from a CSV file hosted on GitHub. The code asynchronously loads the CSV, trims the rows, and parses the numeric door counts before constructing the line chart with green coloring and a legend positioned at the top.
