A scatter plot visualizes modern mathematicians, statisticians, computer scientists, engineers, inventors, biologists, and physicists born after 1950 across seven countries, mapping historical prominence index (hpi) and lifespan (l) on the axes. Each point’s color and fill encode occupation, shape indicates birth country, and size reflects non-English page views. The example uses the Vega-Lite API to construct the specification programmatically, with D3’s `csv` loading data from the Pantheon.world dataset, and renders through Vega with tooltip support.
