This scatter plot visualizes the change in per-capita GDP for various countries from 1800 to 2100. A logarithmic scale on the y-axis reveals the wide range of economic output, from under 500 to over 25,000 dollars, with individual points representing a country-year pair. Built using D3 v7, the visualization uses `csvParse` to load the wide-format Gapminder Foundation data, transforms it into a long format, and renders each data point as a semi-transparent circle, with linear and log scales for the temporal and GDP axes, respectively.
