This visualization shows the population of cantons in Costa Rica as a dot plot, with each circle positioned along the x-axis by population magnitude and the y-axis by canton name. It uses d3.csv to load the data, d3.scaleLinear for the x-axis, and d3.scalePoint for the categorical y-axis. The SVG rendering includes axis labels, a title, and a grid created with d3.axisBottom and d3.axisLeft.
