This scatter plot displays the latitude and longitude of thousands of US post offices, with each semi-transparent circle representing a single location. Built with D3 v6 and SVG, it maps the dataset’s geographic coordinates onto linear scales using `d3.scaleLinear` and `d3.extent`, rendering circles with a radius of two pixels. The axes are generated with `d3.axisLeft` and `d3.axisBottom`, while the data is loaded asynchronously from a CSV file hosted in a GitHub gist. The visualization reveals the density of post offices across the continental United States, with clusters forming along the East and West coasts.
