This example demonstrates a Vega-Lite API template that displays a bar chart comparing Facebook usage and internet penetration across countries. The visualization encodes the Facebook date on the x-axis, internet users on the y-axis, and internet penetration as color, with tooltips showing country names. The code uses the vega-lite-api library with Vega, Vega-Lite, and d3.csv for data loading. Custom configuration enhances readability with larger font sizes and a dark color scheme, while the chart automatically fits the browser window dimensions.
