This example renders a bar chart of country populations using the Vega-Lite API, with data loaded from a CSV via D3’s `csv` function. The chart shows population counts per country, sorted descending, using `vl.markBar()` and encoding fields for country and population. The code integrates Vega-Lite with D3 v6, configures axis styling and tooltips via Vega Tooltip, and resizes the visualization to fit the window. The data originates from the UCI Auto MPG dataset, though the actual values shown come from a population-by-country gist.
