This example visualizes the distribution of population by country using a scatter plot, with points colored by percentage and positioned along a categorical country axis and quantitative population axis. It loads data from the UCI Auto MPG dataset via a Gist, though the code references CSS named colors and population fields. Built with the Vega-Lite API, the visualization registers Vega and Vega-Lite, configures an SVG renderer with tooltips, and applies a custom dark theme for improved readability. The chart uses a point mark with reduced opacity and a zero-less scale to highlight population differences.
